Donald Sterling’s Cancer Revelation Is Suspiciously Timed (WebProNews)
Did Donald Sterling release his medical condition to the press in a bid for sympathy? With the negative publicity surrounding him, the announcement on Thursday that Sterling is battling prostate cancer is seen by more cynical observers as almost conveniently …

He has a stressful job and is concerned that the therapy may affect his ability to work at some stage.
Has anyone reading this had this treatment? What, if any, side effects did you experience and how were they treated?He is 60 and the cancer was detected in its very early stages.
•Medicines such as diuretics
•Overactive bladder syndrome
•Prostatitis (infection of the prostate gland)
•Stroke and other brain or nervous system diseases
•Tumor or mass in the pelvis
Less common causes:
•Radiation therapy to the pelvis, used to treat certain cancers
•Urinary tract fistula
Drinking too much before bedtime, especially caffeine or alcohol, can cause frequent urination at nighttime. Frequent urination may also simply just be a habit.
thank you so much
Internal radiation, or brachytherapy, involves radioactive material that is implanted in the body at the tumor site. Radiation implants are small tubes, seeds or capsules filled with different types of radioactive material and sealed.
Sources of radiation
The more common sources of radiation used for cancer treatment are:
•High-energy photons that come from radioactive sources such as cobalt, cesium, or a machine called a linear accelerator (or linac, for short). Photon beams of energy affect the cells along their path as they pass through the body to get to the cancer. This is by far the most common type of radiation treatment in use today.
•Electron beams or particle beams are also produced by a linear accelerator. These are used for tumors close to a body surface since they do not go deeply into tissues.
•Proton beams are a newer form of particle beam radiation. Protons are charged parts of atoms that cause little damage to tissues they pass through but are very good at killing cells at the end of their path. This means that proton beams may be able to deliver more radiation to the cancer while causing fewer side effects to normal tissues. Protons are used routinely for certain types of cancer, but still need more study in treating others. Some of the techniques used in proton treatment can also expose the patient to neutrons (see below). Proton beam radiation therapy requires highly specialized equipment and is currently only offered in certain medical centers. See the section, “What’s new in radiation therapy?” for more about protons.
•Neutron beams are used for some cancers of the head, neck, and prostate and for inoperable tumors. They can sometimes be helpful when other forms of radiation therapy don’t work. Very few facilities in the United States offer this type of treatment. Its use has declined over the years partly because of problems with getting the beams on target. Because neutrons can cause more DNA damage than photons, the effects on normal tissue may be more severe. Beams must be aimed carefully and normal tissue protected. Neutron beams are showing great promise in research with salivary gland cancers that can’t be cured with surgery.
The cell cycle and radiation
The cell cycle phase is important in cancer treatment because usually radiation first kills the cells that are actively or quickly dividing. It doesn’t work so fast on cells that are in the resting stage (G0) or are dividing slowly. The amount and type of radiation that reaches the cell and the speed of cell growth affect whether and how quickly the cell will die or be damaged. The term radiosensitivity describes how likely the cell is to be damaged by radiation.
Cancer cells tend to divide quickly and grow out of control. Radiation therapy kills cancer cells that are dividing, but it also affects dividing cells of normal tissues. The damage to normal cells causes unwanted side effects. Each time radiation therapy is given it means balancing between destroying the cancer cells and minimizing damage to the normal cells.
Radiation does not always kill cancer cells or normal cells right away. It might take days or even weeks of treatment for cells to begin dying, and they may continue to die off for months after treatment ends. Tissues that grow quickly, such as skin, bone marrow, and the lining of the intestines are often affected right away. In contrast, nerve, breast, and bone tissue show later effects. For this reason, radiation treatment can have long-term side effects that might not be seen until long after treatment is over.
In the past, it was thought that once an area was treated with radiation it could not be treated with radiation again because of damage to the normal cells in the treatment area. But research suggests that a second course of radiation therapy can be given to some patients.
Radiation is used in relation to blood cancers, masses & attached tumors for lung, prostate, brain, leukemia, lymphoma, colon, breast, abdominal, thyroid, liver, bone, esophagus etc.
