A 62-year-old male asked:

cancer: there are about 100 different types of cancer. about how many have screening tests that initially diagnose the existence?

Dr. Dean Giannone

An unfortunate few.: Very few types of cancer, perhaps only two or three really, have valid, proven means of screening, and even those are not perfect. One of the biggest limitations in our knowledge in medicine is the prediction of cancer.

Provided original answer
I was referring to the Cari-free System where the teeth are swabbed, the swab is placed in a special solution, shaken, and placed in a calibrated electronic device that measures the activity level of the bacteria on the tooth. There are studies to validate that the number reported correlqtes with a predication of future caries incidence.

Can multiple lipomas be treated safely w/ steroid injection. I have 50+ & don't want scars. I can live with most but many are large & uncomfortable.?

Not really: Steroid injections will not dissolve lipomas. If you have 50+ they may not be lipomas, some times subcutaneous neurofibromas look like lipomas, you should have biopsy of one lesion to establish diagnosis, these lesions run in families other alternative see a cosmatic surgeon, for possible removal like liposuction.

Liposuction can be used to address lipomas, but there is a much higher risk of recurrence than with a surgically removed lipoma.

My sister just diagnosis with grade 3 endometrial cancer with clear cells why are clear cells so aggressive?

Various cell types: Endometrial cancer is characterized by stage and cell type. Clear cell is a description of the type of cells and simply behave in a more aggressive growth pattern than others.
Dr. Lester Thompson

The clear cell doesn't make it more aggressive, but it is a description of the cell type. Endometrial or ovarian cancer when it is poorly differentiated (grade 3) has a more aggressive behavior, made more so when stage is include (extent of disease).

Husbnd has stg 4 cirrosis liver cncer, I know the cirrosis is stage 4 but confused about how severe (what stage) liver cancer is?

2 doctor answers3 doctors weighed in
Dr. William A Biermann

Hard to say: Typical staging of cirrhosis is by a, b, c and not numbers. There might be another scale that they are using. Liver cancer is associated with cirrhosis. Stages are 1-4. I think that the best way to know is to clarify with the GI doctors to get a clear idea.
