Omental cancer following ovarian ca 7yrs ago w/o chemo or radiation?

Omental cancer following ovarian ca 7yrs ago w/o chemo or radiation?

Your question?: Hi. From what you've told us, I assume you're wondering if the cancer in the omentum is recurrence of the ovarian cancer 7 years ago. First of all, I'm so sorry for your situation. A pathologist will be able to tell you if the omental cancer is ovarian in origin. The best guess (and guessing doesn't count) would be ovarian, however. When the surgical pathology comes back, chemo will be planned. ...Read more

Dad,Oscar,was told stage 4 lung cancer 2.5 wks ago. 1/3 sz brain tumor removed. 3 brain lesions. In bones&pos liver. Would u cyperknife brain tomorrow?

Dad,Oscar,was told stage 4 lung cancer 2.5 wks ago. 1/3 sz brain tumor removed. 3 brain lesions. In bones&pos liver. Would u cyperknife brain tomorrow?

It depends: If you are 76, your Dad must be late 80s or early 90s. At such an advanced age it may not be worth being so aggressive with terminal cancer that at such advanced stage means he has only few weeks to few months left. However, if his desire is to be aggressive, Cyberknife is an effective an low risk procedure and I would recommend it highly. Otherwise, hospice care is very appropriate. ...Read more

32 yo, breast cancer stage 1b, double mastectomy, micrometastasis in one lymph node. TCH treatment, followed by radiation. Prognosis thoughts????

32 yo, breast cancer stage 1b, double mastectomy, micrometastasis in one lymph node.  TCH treatment, followed by radiation. Prognosis thoughts????

Prognosis is good!: I would need more information to be definitive but with a small primary tumor (stage 1) and only micrometastasis in one node, your prognosis should be relatively good. Since you received TCH, it is obvious that you had her2 positive breast cancer so your prognosis is less favorable than had her2 not been positive. However, 5 year survival in excess of 85% is shown in recent studies with TCH. ...Read more

Lumpectomy and radiation last year. Was small amt of cancer in node. Now small shadow on upper right lung CT but radiation on left side. Lung cancer?

Difficult to say: small shadow can be many different things. In the absence of old studies this could have been there for years. Old study is crucial before jumping to conclusions. Old granulomas from old infections can present the same way. It is best to err on the side of caution and have a follow up study to see if it changes before jumping to conclusions. ...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?

"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. ...Read more
