Treatment options for Colorectal Cancer
Following are the common treatment options for colorectal cancers.
Surgery is generally the preferred first line of intervention for colorectal cancer, specially for early stage cancers. The tumor is removed and adjacent lymph nodes could also be removed. The bowel is usually sewen back but sometimes rectum is removed and colostomy bag is used to collect stools.
Chemotherapy is the use of anti-cancer drug that helps to slow or stop the growth of rapidly dividing cells that cause cancer. It prevents the growth of rapidly dividing cells by killing the dividing cells.
Despite its side effects, chemo is still the most widely used cancer treatment option. Unlike radiation and surgery which treats cancer cells at particular locations, chemotherapy drugs can kill cancer cells that have metastated (spread) to different organs in the body.
Targeted Drug Therapy
Targeted therapy is a type of cancer treatment that uses cancer drugs. However, it is different from traditional chemotherapy, which also uses drugs to kill cancer cells. In Targeted therapy, the cancer’s specific genes, proteins, or the tissue environment that contributes to cancer growth and survival are targeted. Targeted therapy is generally used with chemotherapy and other interventions.
