Colorectal cancer and best/worst foods for colorectal cancer
Colorectal cancer is a kind of cancer that affects the colon and rectum.
In 2021, the American Cancer Society (ACS) predicts that 104,270 new cases of colon cancer and 45,230 new cases of rectal cancer will be diagnosed in the United States.
The rate of occurrence varies from country to country. It is more prevalent in nations with a better economic position, but it is also more likely to harm low-income persons, according to a 2021 Source.
Medical advancements have resulted in a decrease in fatality rates. Also, according to the 2021 research, the number of diagnoses is increasing among persons under the age of 50, presumably as a result of improved screening.
Learn about the signs of colorectal cancer and how to treat it in this article. Find out about the risk factors as well, some of which may be avoided.
If so, they might include:
- bowel habits have changed
- a sensation that the intestine does not empty correctly blood in feces that makes it seem dark brown or black bright red blood from the rectum abdominal discomfort and bloating feeling full, even though it has been a long time since a meal
- weariness or exhaustion
- unexplained Anemia due to weight reduction
If a doctor notices indications of anemia during a regular physical examination, they may recommend colorectal cancer screening. Others are diagnosed as a result of regular screening. Around 40% of patients with this kind of cancer are diagnosed when it is still in its early stages.
Symptoms might be similar to those of a variety of different illnesses. Anyone who is concerned about these symptoms should consult a physician.
Early warning indications
Following a report of symptoms, persons who are diagnosed with colorectal cancer are more likely to:
- Source you can trust 37% of the time blood in the feces or in the rectum
- Abdominal discomfort affects 34% of people.
- Anemia affects 23% of the population.
Those who get the diagnosis after seeking emergency medical help include:
- 57 percent of people have a bowel obstruction.
- Peritonitis, or inflammation of the stomach lining, affects 25% of the population.
- A perforation, or hole in the intestine, affects 18 percent of people.
Some patients do not have symptoms until cancer has progressed to the lungs, liver, or other organs. The symptoms vary depending on the part of the body that has been damaged.
When cancer spreads to the liver, it can induce jaundice, which causes the whites of the eyes to turn yellow. The skin of a person with a white or light brown complexion might seem yellowish. If a person’s lungs are affected by cancer, he or she may have trouble breathing or cough.
These are some of them:
the size and location of tumors, as well as cancer’s stage and if it is recurring, as well as the person’s general health Chemotherapy, radiation therapy, and surgery are all possibilities for treatment. Palliative care can help patients cope with symptoms like pain and enhance their overall quality of life.
Colorectal cancer that is confined to the colon is treated mostly with surgery. Its goal is to remove the malignant tissue, including tumors and lymph nodes in the surrounding area, and prevent cancer from spreading. The surgeon generally sews the intestine back together, although a stoma and colostomy bag may be required for drainage. Surgery may be able to eradicate all signs of cancer in its early stages. Surgery cannot stop cancer from progressing in its later stages, but it can help relieve symptoms by eliminating a blockage.
Chemotherapy medicines are used to kill malignant cells all throughout the body. This might aid in the treatment of colon cancer or the reduction of a tumor prior to surgery. In the latter phases, it can also assist alleviate discomfort. However, because it targets both malignant and healthy cells, this method has the potential to cause broad harm.
Therapy that is specific to the patient
This is taking medicines that target certain proteins in order to delay or stop malignant cells from growing. Because these medicines exclusively target particular cells, the side effects are typically less than those of chemotherapy.
This medication aids the body’s immune system in detecting and eliminating malignant cells. Some patients with advanced colorectal cancer may benefit from it. An autoimmune response, in which the body mistakenly targets its own cells, is one of the possible side effects.
High-energy radiation beams are used in radiation treatment to kill malignant cells and prevent them from replicating. It may be suggested by a doctor to help reduce a tumor before rectal cancer surgery. They may also use it in conjunction with chemotherapy, a technique called chemoradiation. It can have both long- and short-term negative consequences.
Microwaves, radiofrequency, ethanol, or cryosurgery are used to kill tumors without removing them.
A probe or needle is used to provide the treatment, which is guided by ultrasonography or CT scans.
End-of-life and palliative care
Colorectal cancer cannot be cured if it spreads to organs other than the colon and progresses to stage 4. Other possibilities include:
- a procedure to clear a blockage
- To shrink tumors, radiation treatment or chemotherapy are used
- a pain reliever
- therapy for medication adverse effects
Vaccines in the future
Scientists are optimistic that a vaccine to treat colorectal cancer will be available shortly.
According to clinical data released in 2019, a vaccination called Ad5-GUCY2C-PADRE may assist patients with colorectal cancer who have not yet reached stage 3 of the disease.
Risk factors and their causes
The precise cause of colorectal cancer is unknown. The majority of instances are most likely caused by a mix of environmental and genetic factors. Around 70% of Trusted Source instances occur for no apparent cause, whereas 10% appear to be inherited and 20% occur in familial clusters.
Other elements that may be involved include:
- being older, male, with a low income, and eating a low-fiber, high-animal protein, saturated fats, and calorie diet
- consuming a lot of red or processed meat
- drinking alcoholic beverages and smoking
- obtaining insufficient physical activity
- having obesity or being overweight
- Irritable bowel disease (IBD)
- having type 2 diabetes and possessing specific genetic characteristics
- having had breast, ovarian, or uterine cancer as a kid having had radiation therapy for abdominal cancer as a youngster having colon or rectum polyps
Polyps can be malignant or precancerous. Learn about one type of polyp that may form in the colon, termed sessile polyps.
African-Americans are at higher danger.
According to a 2018 study, Black Americans are more likely than any other group in the United States to acquire and die from colorectal cancer.
According to the ACS report, a Black person’s probability of getting this form of cancer is at least 20% greater than a white person’s, and the mortality rate is 40% higher for Black people.
The ACS mentions socioeconomic issues and disparity in terms of screening particularly and healthcare in general, as well as work, nutrition, and other daily living aspects in explaining the causes.
According to the authors of the 2018 study, further research is needed to determine whether colorectal cancer affects Black individuals differently and that this research might lead to more effective therapy.
The extent to which cancer has spread is determined by its stage. Doctors can choose the most appropriate treatment by determining the stage.
Staging may be done in a variety of ways. One approach is to:
At this stage, the cancer is limited in the inner layer of the colon or rectum, referred to as carcinoma in situ.
1st Stage: Cancer has spread to the inner layer of the colon or rectum but has not spread beyond the rectum or colon’s wall.
2nd Stage: Cancer has spread through or into the colon or rectum wall, but has not yet spread to the lymph nodes nearby.
3rd Stage: Cancer has spread to surrounding lymph nodes but not to other organs.
4th Stage: Cancer has spread to other organs such as the liver or lungs.
Treatment may eradicate cancer, but it may reappear in the same or another place of the body. Recurrent cancer is the term for this.
Polyps can be detected using screening before they become malignant. It can also detect colon cancer in its early stages when treatment is more effective.
A doctor identifies colorectal cancer after performing a colonoscopy in 80 percent of instances because the person has symptoms. Routine screening catches 11% of cases, while 7% of patients with colorectal cancer are diagnosed after seeking emergency medical attention for acute stomach symptoms.
The most frequent colorectal cancer screening and diagnostic sources are listed below.
Colonoscopy is the gold standard for colorectal cancer diagnosis. It has a high level of precision and can pinpoint the exact location of a tumor.
A colonoscopy, a long, thin, flexible instrument with a light and a camera, is used during the operation. It gives the clinician a clear view of the whole colon and rectum. During the operation, they may remove polyps or collect tissue for a biopsy.
Although a colonoscopy is pleasant, some patients choose to take a little sedative to help them relax. A person may need to consume a laxative solution before the procedure to clear out their colon. Bleeding and colon wall perforation are uncommon but possible consequences.
Test for blood in the stool
This test detects the presence of blood in a feces sample. This problem can be caused by a variety of factors, and it does not necessarily indicate that cancer is present. A stool sample might be collected at home or at work.
Immunochemistry of feces
This test, often known as a fecal immunochemistry test, examines the lower intestine for concealed blood. It entails collecting a stool sample at home with a little kit.
A DNA test of the feces
This test looks for a number of DNA markers that colon tumors and precancerous polyps excrete in their feces. At home, a person collects an entire bowel movement for laboratory testing. A colonoscopy is required if the result is positive.
It’s important to remember that this test can’t detect every cancer-related DNA signature.
The rectum and sigmoid colon – the final portion of the colon before the rectum — are examined with a sigmoidoscopy, a flexible, thin, illuminated tube.
The test just takes a few minutes and is not painful, but it might be unpleasant. There’s a chance you’ll perforate the colon’s wall.
Enema with barium X-ray
On an X-ray, barium is a contrast dye that can highlight any odd characteristics. As an enema, a healthcare practitioner administers it to the colon.
Following a barium enema X-ray, a doctor may prescribe a colonoscopy for further study.
Colonography using computed tomography
This results in colon images. Although it is less intrusive than a colonoscopy, if a mass is discovered, the person will require a colonoscopy.
If cancer has spread to another region of the body, ultrasound, CT, or MRI scans can reveal it.
Foods to eat and avoid
Diet Has an Impact
For both men and women, colorectal cancer is the third most prevalent kind of cancer. It’s possible that making smart dietary choices can help you reduce your risks of contracting it. According to some studies, persons who eat well, exercise often, maintain a healthy weight, and use little alcohol reduce their risk of developing the illness by more than a third.
Consume dairy products
The majority of research agrees that calcium-rich dairy products reduce the risk of colon growths (adenomas) and colorectal cancer. Supplementing with calcium may also be beneficial. Consult your doctor to see what options are available to you. More study is needed to see if vitamin D (which is added to milk) can help prevent this form of cancer.
Consume Whole Grains
These are high in nutrients and an excellent source of fiber and magnesium. They keep your feces moving, and they may pick up cancer-causing chemicals in your colon along the way. Aim for 90 grams of whole grains each day, which may be found in oatmeal, whole wheat bread, and brown rice.
These, as well as other legumes (such as soybeans, peas, and lentils), are high in fiber, protein, and vitamins B and E. They also include flavonoids, which can help prevent tumor growth, as well as antioxidants that may help protect you from colon cancer. Make a substantial soup or substitute black beans for one of your typical side dishes.
Consume: A Variety of Colorful Fruits and Vegetables
These include natural compounds (phytochemicals) that may inhibit cancer cell development or combat inflammation, both of which can feed cancer. Although there has been conflicting evidence associating fruits and vegetables with the prevention of colon cancer, cancer groups still suggest them as part of a balanced diet. Broccoli, cabbage, and Vitamin-C-rich fruits like oranges are all good choices.
Fatty fish, such as salmon, are high in omega-3 fatty acids, which are good for heart health and may inhibit cancer cell development. However, it’s unclear if eating fish can help prevent colorectal cancer. People who ate fish instead of red meat were less likely to get rectal cancer, according to several studies. Swordfish, tuna, tilefish, shark, and king mackerel are all prohibited. They might include mercury and other contaminants that are harmful to your health in the long run.
Red Meat Is Off Limits
While a delicious burger fresh off the grill may entice your taste buds, it might be harmful to your intestines. Scientists know that eating red meat on a regular basis, such as beef, pig, and lamb, increases your risk of colorectal cancer, but they don’t know why. It might be due to the meat itself, or it could be due to cancer-causing chemicals forming when it’s cooked at high temperatures. Aim for a weekly intake of fewer than 18 ounces.
Processed meats are off-limits
These are meats that have been smoked, cured, salted, or chemically preserved. Hot dogs, bacon, ham, bologna, and packed lunch meat are just a few examples. Consuming such meats on a regular basis might increase your risk of colon and stomach cancer.
Alcohol is prohibited
A few drinks here and there do not appear to increase your risk of colon cancer. However, moderate to heavy drinking (two or three glasses per day) can increase your odds of getting it by 20%, and excessive drinking can increase your chances by 40%. If you drink more than three drinks per day on a regular basis, talk to your doctor about getting screened for colorectal cancer.
We don’t know if coffee, tea, caffeinated beverages, sugary meals, potatoes, and garlic, among other things, play a role in developing or preventing colorectal cancer. There will almost certainly be further research on the link between food and colorectal cancer in the future.
Take care of yourself
The majority of our health problems are caused by bad eating habits and lifestyle choices. To stay in good health and keep illnesses at bay, you need to eat healthy, homemade, and nutritious meals. When it comes to chronic illnesses like colon infection, your food choices are crucial.
Colon infection, often known as colitis, is an inflammation of the colon’s inner lining (large intestine). It is a frequent illness that affects both men and women. It can be caused by a variety of factors, including infection, inflammatory bowel disease, and an allergic reaction. Colon infection can progress to colon cancer depending on its intensity and kind.
Bad sugary stuff
Food that contains a lot of refined sugar is never beneficial for your health. It can cause a variety of health problems, including diabetes, obesity, and even colon infection. Researchers have discovered a connection between sugary foods and colon illnesses. As a result, reducing your sugar intake is a good suggestion.
Bad processed food
Processed food that is greasy, spicy, and heavy in saturated fat is thought to be detrimental to your colon health. Furthermore, several chemicals are utilized to preserve and prepare such food products, which may be harmful to your stomach and intestines. Excessive consumption of processed foods is much worse for your heart’s health.
Bad caffeine and alcohol
Having one cup of coffee or one drink each week is not harmful; the true issue arises when you become hooked to it. Excessive coffee or alcohol use can irritate the stomach lining, resulting in illness. It may also cause acid reflux, heartburn, and difficulty swallowing.
Beans are high in fiber, Vitamin E, Vitamin B, and protein, all of which are beneficial to colon health. They also include flavonoids, which can aid in the prevention of inflammatory illnesses such as colon infection. Beans are also high in antioxidants, which aid in the healing of damaged cells in the body.
Flaxseed, which is high in minerals and dietary fiber, is a good meal for a healthy colon. Flaxseed reduces inflammation by inhibiting the production of pro-inflammatory cytokines and lipid mediators. It also aids in the removal of toxins from the colon and the prevention of digestive problems.
Include papaya in your diet if you frequently get stomach problems. This fruit is always recommended for people who have constipation or digestive problems. Papaya includes lubricants and enzymes that help to keep your colon clean and healthy.
