How long is your immune system compromised after radiation?
Within the T-cell population a subset with helper/inducer phenotypes, detected by Leu-3a antibodies, was significantly reduced even 10-11 years after irradiation. T-cells with suppressor/cytotoxic phenotypes, stainable with Leu-2a antibodies, however, had already recovered 5-6 years after irradiation.
Why does radiation therapy make you so tired?
Most people start to feel tired after a few weeks of radiation therapy. This happens because radiation treatments destroy some healthy cells as well as the cancer cells. Fatigue usually gets worse as treatment goes on. Stress from being sick and daily trips for treatment can make fatigue worse.

How long does it take for a tumor to shrink after radiation?
At the same time, if a cell doesn't divide, it also cannot grow and spread. For tumors that divide slowly, the mass may shrink over a long, extended period after radiation stops. The median time for a prostate cancer to shrink is about 18 months (some quicker, some slower).

Overview
Why It's Done
- Proton therapy is used as a treatment for cancer and some noncancerous tumors. Proton therapy may be used as the only treatment for your condition. Or it may be used in conjunction with other treatments, such as surgery and chemotherapy. Proton therapy may also be used if the cancer remains or comes back after traditional X-ray radiation. Proton therapy is sometimes used to treat: 1. Brain tumors 2. Breast cancer 3. Cancer in children 4. Ey…
Risks
- Proton therapy can cause side effects as the cancer cells die or when the energy from the proton beam damages healthy tissue near the tumor. Because doctors can better control where proton therapy releases its highest concentration of energy, it's believed to affect less healthy tissue and have fewer side effects than traditional radiation therapy. Still, proton therapy does release some of its energy in healthy tissue. The side effects you exp…
How You Prepare
- Before you undergo proton therapy, your health care team guides you through a planning process to ensure that the proton beam reaches the precise spot in your body where it's needed. Planning typically includes: 1. Determining the best position for you during treatment. During radiation simulation, your radiation therapy team works to find a comfortable position for you during treatment. It's important that you lie still during treatment, so …
