Rectal cancer develops in the rectum, the last part of the large intestine just before the anus. It is a common form of colorectal cancer and often requires a carefully planned, multidisciplinary treatment approach. Early detection through screening and prompt medical attention significantly improves treatment success and long-term outcomes.
Radiation therapy plays a crucial role in the management of rectal cancer. It is commonly used before surgery (neoadjuvant therapy) to shrink the tumor, improve surgical outcomes, and reduce the risk of local recurrence. In certain cases, it may also be used after surgery or in combination with chemotherapy for advanced disease.
Treatment planning involves detailed clinical evaluation along with imaging studies such as MRI of the pelvis, CT scan, and sometimes PET-CT to determine the stage and extent of the disease. Based on findings, a combination of therapies may be recommended.
Modern techniques such as IMRT and IGRT allow highly precise radiation delivery to the rectal tumor while minimizing exposure to nearby organs such as the bladder, small bowel, and reproductive organs. This helps reduce side effects and improves treatment tolerance.
With early diagnosis, personalized treatment planning, and coordinated multidisciplinary care, rectal cancer can be effectively managed, leading to improved survival rates and better quality of life.
