Colorectal cancer is a type of adenocarcinoma that starts in the mucus-producing glandular cells of body. The vital function of glandular glands is the secretion of substances produced by it. Colorectal cancer is also called colon or rectum cancer. The colon is a large intestine of the body. This cancer occurs when the tumor of cancer starts growing in the inner wall of the large intestine. Due to inaccuracy or fault in cell division formation the abnormal cells of cancer cells starts to grow and divide in the colon called a polyp. Cancer begins as a polyp in the large intestine which can be detected by the colonoscopy. The colon draws out the water and salt from the solid waste and moves the wastes through the rectum to throw it out-of-body. Colon cancer causes severe complications if early symptoms and signs are ignored. In 2018 there were 2 million cases of colorectal cancer were found in the world.

Another cause of colorectal cancer is genetics and the history of this cancer in family members. Chromosomes of cells contain genetic information and damage to genetic effects can lead to the formation of polyps and cancers. The 20 out of 100 people diagnosed with colorectal cancer have a family history of this cancer.

Surgery is possible to remove the cancerous polyps which are attached to the walls of the colon or polyps are detected in the lining of the colon. It also removes the surrounding part where cancerous polyps have spread. This surgery is called the colostomy. The other surgeries such as endoscopy, laparoscopic, palliative surgery can be used to remove the polyps.

Chemotherapy is used to destroy or kill the cancerous cells in the colon or rectum. It can be also used after surgery to kill the remaining cancer cells. It is used in the last stages of cancer to limit the growth of cancerous polyps.

Radiation therapy is used to kill the cancer cells by using high energy gamma rays on them. It is used along with other treatments and advanced stages but in early stages, it can also be used if the tumor penetrated the rectum wall.

The medications which can be used along with the treatment are Avastin, Bevacizumab, Camptosar, Cetuximab, Cyramza, Eloxatin, Erbitux, etc. To buy prescription cancer medicines online3Meds is the best medical online store.
