What are the symptoms of early rectal cancer

What are the symptoms of early colorectal cancer?

Rectal cancer is caused by cancer in a certain part of the colorectum and is one of the common malignant tumors in the digestive system. In China, it is also a cancer with a high incidence rate, second only to gastric cancer and esophageal cancer. We all know that cancer cannot be treated in the early stage, and there is no way to treat it in the late stage. We can only live one day at a time.

What are the early symptoms of rectal cancer?

1. Red stool

In most cases, rectal cancer has no symptoms in the early stages, does not affect the normal functioning of the body, and does not cause discomfort to the body. But the stool will turn red. We all know that normal stool is golden yellow or stool yellow, and red stool will not appear if you do not eat pigmented foods.

Some people say that hemorrhoids can cause blood in the stool, but hemorrhoids can be left untreated, which leads to the early symptoms of rectal cancer being misunderstood as hemorrhoids and ignored, ultimately delaying treatment. When blood often appears in the stool, we should be careful not to feel any disease, but do an accurate examination to confirm the cause.

2. Black and purple stool

After you get rectal cancer, cancer cells will block the intestines more and more during the reproduction process, causing the stool to stay in the rectum for a long time and turn black. The stool discharged from the body will be abnormal in color, which is an uncommon black purple or dark purple. But you don't have to worry about one or two black purple stools for a long time. If you have black purple stools several times in a row recently, you should check whether there are early symptoms of rectal cancer in time.

3. The stool becomes as thin as earthworms

When cancerous tumors grow larger in the small intestine, it can cause difficulty in defecation, and the stool becomes thinner and thinner, like earthworms. However, some people feel pain during defecation due to physical problems, some of which are mild and sometimes more severe.
