What is the probability of inheriting colorectal cancer

The cause of rectal cancer is very complex. The treatment of rectal cancer mainly relies on reducing the chance of canceration and early detection of patients. What is the probability of rectal cancer inheritance? Medical research believes that rectal cancer is a multi-gene genetic disease, and its occurrence is mainly related to environmental factors and genetic factors. Family history is the most direct manifestation of genetic factors, and the risk of cancer is closely related to family history.

What is the genetic probability of colorectal cancer?

Seventy to eighty percent of colorectal cancers have no clear genetic background, and this type of colorectal cancer is called sporadic colorectal cancer. The remaining approximately 20 to 30 percent have a family history of colorectal cancer and have a tendency to cluster in the family, which is called genetically related colorectal cancer. Medical research believes that colorectal cancer is a multi-gene genetic disease, and its occurrence is mainly related to environmental and genetic factors. Family history is the most direct manifestation of genetic factors, and the risk of cancer is closely related to family history. Moreover, the intensity of the risk is related to the number of relatives with colorectal cancer in the family history, whether they are first-degree relatives, and the age of onset. The specific manifestations are:

(1) Three or more family members have colorectal cancer, two or more of whom are from the same generation;

(2) At least two generations of the same family have been diagnosed with the disease;

(3) At least one of them was diagnosed with colorectal cancer before the age of 50.

How to prevent colorectal cancer?

(1) Actively prevent and treat rectal polyps, anal fistulas, anal fissures, ulcerative colitis and the stimulation of chronic intestinal inflammation; for multiple polyps and papillary polyps, early surgical removal should be performed once the diagnosis is clear to reduce the chance of canceration.

(2) Diversifying your diet and developing good eating habits, not being partial or picky about food, and not consuming high-fat, high-protein foods for a long time. Regularly eating fresh vegetables containing vitamins and fiber may play an important role in preventing cancer.

(3) Prevent constipation and keep bowel movements smooth.

(4) Attach great importance to regular cancer prevention surveys, pay attention to self-examination at all times to increase vigilance, and seek timely diagnosis and treatment after discovering "warning signals" to achieve early detection and early treatment to improve the survival rate of rectal cancer.

Once rectal cancer patients are diagnosed, they need to go to the hospital for treatment, otherwise many complications will occur in the later stage. Patients should eat a reasonable diet and eat less greasy and spicy food.
