Radiation therapy is a highly effective and proven method for treating breast cancer. This treatment uses high-powered radiation to destroy cancer cells. Often used alongside surgery or chemotherapy, radiation therapy helps eliminate cancer cells entirely and reduces the risk of the disease returning.
How Does Radiation Therapy Work?
Radiation therapy uses a form of X-rays or gamma rays to damage the DNA of cancer cells. As a result, the cancer cells lose the ability to divide and spread, gradually leading to their destruction. Radiation therapy is generally administered in two ways:
- External Beam Radiation Therapy: In this method, radiation is directed at the external part of the breast using a machine. Typically, this therapy lasts 10-15 minutes each day for 3-5 weeks.
- Brachytherapy: In this method, a small radiation source is placed inside the breast, directly targeting and destroying the cancer cells.
When is Radiation Therapy Needed?
Radiation therapy is usually applied in the following situations:
– After Lumpectomy: After removing the cancer-affected part, radiation is applied to the remaining breast tissue to prevent cancer from recurring.
– After Mastectomy: If there is a risk of cancer spreading after the complete removal of the breast, radiation therapy is used.
– If Lymph Nodes are Affected: If cancer spreads to the lymph nodes, radiation therapy can be effective in destroying those cancer cells.
Side Effects of Radiation Therapy
Although radiation therapy is generally safe, some side effects may occur, such as:
Immediate (Acute) Side Effects:
– Redness or darkening of the skin at the treatment site.
– Feeling of fatigue or weakness.
– Increased sensitivity in the chest or skin.
Delayed Side Effects:
– Heart disease or lung problems (rare).
Doctor’s Advice and Care
It is important to follow the doctor’s advice both during and after radiation therapy. Proper rest, eating healthy food, and taking care of your skin are essential after treatment.
Radiation therapy is a vital part of breast cancer treatment. It helps improve the quality of life by reducing the risk of cancer recurrence. By following medical guidance and staying aware, you can fully benefit from this treatment process. With the right treatment and mental strength, it is possible to fight breast cancer.
