Radiation Therapy

---

Radiation therapy is also called as Radiotherapy, is a dominant cancer treatment that uses high level of ionizing radiation to terminate cancer cells and decrease tumor size. Although lesser amount of radiation is often used for diagnostic imaging like X ray, therapeutic radiation aims to exactly target and eradicate cancerous cells.

This therapy functions by damaging the DNA of cancerous cells, preventing their growth and resulting in their death. To minimize the damage to healthy tissues, radiation is applied from various angles, focusing a strong dose on the tumor while lessening contact to adjacent organs and tissues. In certain cases, the radiation area may involve lymph nodes if they are supposed to be involved with cancer or if there is a possibility of microscopic dissemination.  

Although radiation therapy is effective in battling cancer, it may also lead to side effects that vary based on the treatment area, quantities and each patient’s response. Some typical side effects involve of skin reactions where the affected area might turn red, become dry, itchy or peel, alike to a sunburn. In certain cases, it might become darker or form blisters. Several patients feel drained during the therapy because the body’s energy is used for recovery. When radiation is used at hairy area like the scalp, it may result in hair loss in the affected region. Radiation directed at the chest may lead to nausea, vomiting.

The use of radiation in the area like head, neck or chest can results in a sore throat, dry mouth and difficult to swallow. In certain occurrence, this therapy can lead in lasting difficulties, including fibrosis, lymphedema or heightening risk of secondary cancers. The common side effects are fleeting and can be handled with medications, lifestyle changes or proper treatment. Patients must ensure to have regular check ups and guarantee the best possible results from the treatment.
