Radiation Therapy For Cancer in Jordan

Radiation therapy uses ionising radiation precisely directed at a defined volume in the body. It damages the DNA of tumour cells so they lose the ability to divide, while geometric and physics planning keeps the exposure of surrounding healthy tissue as low as possible. It is delivered either from outside the body by a linear accelerator, or from inside using sources placed temporarily or permanently near the tumour. Radiation is prescribed for several distinct purposes: as a curative treatment on its own in certain tumours; before surgery to shrink a tumour and make removal feasible; after surgery to reduce the chance of local recurrence; alongside systemic drug treatment to strengthen the effect; or palliatively, to relieve pain from bone metastases, stop bleeding, or relieve pressure on an airway or the spinal cord. The decision is made by a multidisciplinary team including the radiation oncologist, surgeon, medical oncologist, radiologist and pathologist, after reviewing the tumour type, stage and site and your general condition. The pathway is highly structured. It begins with a planning and simulation session in which the area is imaged by CT in the exact treatment position with immobilisation devices, and precise skin marks or small permanent marks are placed. A medical physicist then calculates the dose and its distribution and verifies the plan before the first session. You then attend short sessions, usually daily from Monday to Friday over a number of weeks. The session itself is painless, you feel nothing during it, and with external beam treatment you do not become a source of radiation afterwards, so you can be with your children and family safely. Care of the irradiated skin is part of the treatment, not a cosmetic extra. Wash the area with lukewarm water and a mild cleanser without scrubbing, pat it dry rather than rubbing, and use only the moisturiser your team recommends, avoiding it in the two hours before a session if you are asked to. Keep perfumes, alcohol-based products, metallic antiperspirants, herbal preparations, oils and home remedies off the treatment area, do not shave the field with a blade, apply no hot packs or ice, protect the skin from sun and from rough or tight clothing, and never rub or try to remove the marks. The limits must be stated plainly. Radiation is a local treatment that acts only within the planned volume, so it does not treat disease outside that volume and does not replace systemic therapy when that is needed. Its effect accumulates gradually and improvement may continue for weeks after the final session. Fatigue, a skin reaction, and site-specific effects such as difficulty swallowing, changes in urination or nausea are common and are managed with a plan, and late effects can appear months later and require long-term follow-up. Suitability, dose and number of sessions are determined by the team, the imaging and the examination, not by reading.
