A growth of cells called colorectal cancer starts in the colon, a section of the large intestine. The first and longest segment of the big intestine is called the colon. The last segment of the digestive system is the large intestine. Food is broken down by the digestive system and used by the body.

Although it can strike at any age, colorectal cancer usually affects older persons. Small cell clusters called polyps that grow inside the colon are typically where it all starts. Although polyps are mostly not malignant, some may eventually develop into colon cancer.

While colorectal cancer can occur at any age, older people are typically affected by it. Usually, it all begins with little cell groupings called polyps that form inside the colon. While most polyps are benign, some may eventually progress to colon cancer.

Should colon cancer arise, numerous therapies can aid in its management. Among the treatments include radiation therapy, surgery, and medications like immunotherapy, chemotherapy, and targeted therapy.

Colorectal cancer is another name for colon cancer. This phrase refers to cancer that starts in the rectum and includes both colon and rectal cancer.

Symptoms

Many patients with colon cancer initially show no symptoms. Symptoms may probably vary depending on the location and extent of the cancer in the large intestine.

Symptoms of colon cancer can include:

  • Weakness or tiredness.
  • Rectal bleeding or blood in the stool.
  • Losing weight without trying.
  • Ongoing discomfort in the belly area, such as cramps, gas or pain.
  • A change in bowel habits, such as more frequent diarrhea or constipation.
  • A feeling that the bowel doesn’t empty all the way during a bowel movement.

 

When to see a doctor

If you notice lasting symptoms that worry you, make an appointment with a health care professional.

Causes

What causes the majority of colon cancers is unknown to doctors.

The development of DNA alterations in colonic cells is the cause of colorectal cancer. The instructions that inform a cell what to do are encoded in its DNA. The alterations instruct the cells to proliferate rapidly. When healthy cells naturally die as part of their lifecycle, the modifications allow the cells to live on.

There are too many cells as a result. The cells may aggregate into a mass known as a tumour. Healthy bodily tissue can be invaded by the cells and destroyed. The cells may eventually separate and disperse to other areas of the body. Metastatic cancer is the term for cancer that spreads.

Risk factors

The following are some factors that may raise your risk of colorectal cancer:

older years. At any age, colorectal cancer can occur. However, the majority of colon cancer patients are over 50. The proportion of colon cancer cases in those under 50 has been rising. Physicians do not know why.

the black race. Compared to other racial groups, black Americans are more likely to develop colorectal cancer.

a personal history of polyps or colorectal cancer. The risk of colon cancer is increased by prior colon cancer or colon polyps.

intestinal inflammations. Inflammatory bowel illnesses, or painful and swollen intestinal conditions, raise the risk of colorectal cancer. Among these ailments include Crohn’s disease and ulcerative colitis.

inherited conditions that raise the risk of colon cancer. Colon cancer risk is increased by certain genetic variations that run in families. The two most prevalent hereditary syndromes that raise the risk of colon cancer are Lynch syndrome and familial adenomatous polyposis.

Family history of colon cancer. The chance of colon cancer is increased if one’s blood relative has the disease. The risk is higher if there are multiple family members with colon or rectal cancer.

high-fat, low-fiber diet. A normal Western diet may be associated with colorectal and rectal cancer. This kind of diet is usually heavy in calories and fat and poor in fibre. The outcomes of this research have been inconsistent. Consuming large amounts of red and processed meat has been linked in certain studies to an increased risk of colon cancer.

Not doing regular exercise. Inactive individuals have a higher risk of colorectal cancer. Engaging in regular exercise may help reduce the risk.

Diabetes. Individuals with insulin resistance or diabetes are more likely to develop colorectal cancer.

Being overweight. Obesity raises the risk of colorectal cancer in individuals. Additionally, colon cancer death risk is elevated by obesity.

smoking. Smokers may be at a higher risk of developing colorectal cancer

consuming alcoholic beverages. The risk of colorectal cancer can rise with excessive alcohol consumption.

cancer treated with radiation. The risk of colorectal cancer is increased by radiation therapy administered to the abdomen for the treatment of prior malignancies.

Prevention

Screening for colorectal cancer

Physicians advise those who have an average risk of colorectal cancer to start screening for the disease around age 45. However, those who are at a higher risk ought to consider beginning screening earlier. Individuals who have a family history of colorectal cancer are at an elevated risk.

A variety of tests are included in the screening process for colorectal cancer . Discuss your alternatives with your medical team.

Modifications in lifestyle to lower the risk of colorectal cancer

Modifications in lifestyle to lower the risk oModest lifestyle adjustments can lower the risk of colon cancer. To reduce the likelihood of colon cancer:f colorectal cancer

Consume a range of whole grains, fruits, and vegetables. Vitamins, minerals, fibre, and antioxidants found in fruits, vegetables, and whole grains may help prevent cancer. To ensure you receive a range of vitamins and nutrients, choose a selection of fruits and vegetables.

If you use alcohol at all, do it in moderation. If you decide to consume alcohol, try to keep your intake to no more than one drink for women and two for men every day.

On most days of the week, work out. Make an effort to exercise for at least half an hour most days. If you haven’t exercised, begin cautiously and increase to 30 minutes over time. Additionally, consult a medical expert prior to beginning an exercise regimen.

Maintain a healthy weight. If you are at a healthy weight, work to maintain your weight by combining a healthy diet with daily exercise. If you need to lose weight, ask your health care team about healthy ways to achieve your goal. Aim to lose weight slowly by eating fewer calories and moving more.

prevention of colorectal cancer in those at high risk

Certain medications may lower the chance of colorectal cancer or colon polyps. For example, there is evidence that regular use of aspirin or aspirin-like medications reduces the incidence of polyps and colon cancer. However, it’s unclear how much and for how long would be required to lower the risk of colon cancer. Daily aspirin use carries certain hazards, such as bleeding in the digestive tract and ulcers.

These choices are typically limited to those who have a high risk of developing colorectal cancer. Insufficient evidence supports the recommendation of these medications for those with an average risk of colorectal cancer.

Consult your healthcare team about your risk factors if you have a higher than average chance of developing colorectal cancer to see whether taking preventive medication is safe for you.
