Characteristics of familial hereditary colorectal cancer

Rectal cancer is a disease that occurs more frequently in people's lives, and it also brings considerable impact and harm to people. It is one of the diseases that we need to pay attention to. We also know clearly that the disease can only be recovered faster if it is treated in the early stage. So what are the characteristics of hereditary rectal cancer? Let's take a look at it together:

1. Changes in bowel habits are the earliest and most common symptom of rectal cancer. Due to the stimulation of rectal cancer tumors, patients with rectal cancer may have an increase in the number of bowel movements for no obvious reason or alternating constipation and diarrhea in a short period of time, with a feeling of incomplete bowel movements. As the disease progresses, the lesions increase in size, and the tumors may block the rectal outlet, causing constipation, thin or deformed stools, abdominal distension and other symptoms. This is one of the early symptoms of rectal cancer.
2. Early symptoms of rectal cancer may include loose stools, blood in the stool, and mucus. 80%-90% of rectal cancer patients may have blood in the stool, which is bright red or dark red, often mixed with mucus and pus. Once rectal cancer patients find the above symptoms, they should go to the hospital for examination immediately. When seeing a doctor, be careful not to easily believe the doctor's conclusions without any examination, such as hemorrhoids or bacillary dysentery. If the doctor does not request an examination, the patient may as well ask for it himself. Generally speaking, digital rectal examination can detect more than 75% of rectal cancers, and electronic anoscopes can detect almost all rectal cancers.
