treatment of colon cancer in delhi –
treatment of colon cancer in delhi – Colon cancer, also known as colorectal cancer, begins in the large intestine (colon) or rectum. It is one of the most common types of cancer worldwide, but the good news is that with early detection and the right treatment, many patients can achieve a full recovery. Understanding the treatment options available is the first step towards fighting colon cancer effectively.
Diagnosis Before Treatment
Before starting treatment, a thorough diagnosis is essential. Tests such as colonoscopy, biopsy, CT scans, MRI, and blood tests (including tumor markers like CEA) help doctors determine the stage and spread of cancer. The stage (ranging from 0 to IV) plays a major role in deciding the best treatment approach.
Main Treatments for Colon Cancer
-
Surgery
Surgery is the most common treatment for colon cancer, especially in the early stages. The type of surgery depends on the size and location of the tumor:
-
Polypectomy and Local Excision: For very early-stage cancers (stage 0 or I), doctors can remove cancerous polyps during a colonoscopy.
-
Colectomy: For larger tumors, a partial colectomy (removing part of the colon) or total colectomy (removing the entire colon) may be performed. Surgeons often reattach the healthy parts of the colon, but in some cases, a colostomy bag might be temporarily or permanently required.
-
Chemotherapy
Chemotherapy uses powerful drugs to kill cancer cells. It is often recommended after surgery to destroy any remaining cancer cells and lower the risk of recurrence, especially in stage II or III colon cancer. In advanced stages (stage IV), chemotherapy can also help control symptoms and prolong life.
