Why is my father getting radiation to his brain when he has lung cancer?

Spread to the brain . Lung cancer often spreads to the brain. So either it has already been seen on scans of the brain and is being treated or in small cell lung cancer we use it prophylactically. That is trying to prevent it from showing up, but that is only the case in small cell lung cancer.
Brain mets. Lung cancer likes to spread to other organs, one of which it usually like to go to is brain. Radiation is often used to treat the brain mets since chemotherapy does not penetrate well because of a blood brain barrier that exists naturally.
Prevention possible. If he has no tumors known "in" his brain, data have shown that treating people with lung cancer prophylacticly gives a survival advantage. Small cell type is the most common type of lung cancer to get this type of radiation therapy.

Dad has metastize lung cancer in his brain. Had radiation but now there is nothing they can do. What will his symptoms be as the cancer takes over?

Depends. It really depends on which part of the brain is involved. He could become paralyzed or blind or possibly unable to speak. Speak with a neurologist about which symptoms would be most likely. Best of luck and sorry to hear about your father's disease. Read more...

What should I expect for small cell lung cancer metastasized to the brain twice. I have been treated with gamma knife as well as whole brain radiation?

Serious illness. Small cell lung cancer is a serious and fatal illness. The 2 brain metastasis episodes are also serious. You, your family and your oncologist need to discuss your prognosis. Read more...
You did not tell us . The brain mets appered at diagnosis or developed after treatment. Presenting with brain metastasis is not favorable. You didn't tell us the interval between wbrt, gamma one or two. Doing things from this point forward should be aimed at producing comfort. No facts suggest that any further treatment will extend your life. Choose comfort. Ask about palliative care focus. Read more...
Watch out. The chance of further brain metastases is very high. You should have an MRI of the brain at least every other month, if not every month. Better to catch these tumors small when they can be treated with radiosurgery instead of more whole brain. Good luck, . Read more...

Life expectancy for lung cancer gone to brain. Pet scan shows no other cancer now, only 1 tumor on brain. Surgery and whole brsin radiation will be?

Factors. Many factors are involved: age, immune system, type of tumor, gender in certain cases, type of chemotherapy , compliance among many others. Your oncologist is the best guide. Read more...
Difficult to say. This is considered an advanced cancer, stage IV or distant metastases stage. As you said, surgery and radiation is the treatment for this. However, as to the outcome, it is difficult to say. The 5 year survival of patients with this stage is <5%, but with just one lesion, and all the advances you never know, so see your doctor/oncologist. Best of luck. Read more...
"oligometastatic" Patients with a single brain tumor as the only site of metastatic disease are called "oligometastatic." the chance of cure, though small, is real. Every cancer specialist has a few such patients. I would strongly recommend aggressive treatment, including either radiosurgery (cyberknife, gammaknife, etc.) to the brain or surgical resection, and again stereotactic or chemoradiation to the lung.

My father was diagnosed as lung cancer with brain metatasis stage 4 last month. He loss of appetite since 6/12 ago. Keep having seizures. What kind of?

Serious problem. Sounds very serious and possibly life-threatening, needs immediate hospitalization until seizures stop. Read more...
The question is not. Clear. His seizures are usually treated with a med like Keppra (levetiracetam) and steroids, and the cause of the seizures (the mets) treated usually with radiation (whole brain radiation or radiosurgery). Once the brain has been treated, we typically offer chemotherapy and potentially more radiation depending on where else the tumor has spread. Appetite loss is hard to treat, but may try steroids or marinol. Read more...
