Are kidney cancer cells different from breast cancer cells and lung cancer cells?

Are kidney cancer cells different from breast cancer cells and lung cancer cells?

Quite Different: These 3 different cancers are actually quite different. Under the microscope they look different, and the types of mutations they have are also different. As a result, the way the different cancers are treated are also different. Generally speaking for kidney cancer they would use targeted therapies or immunotherapies instead of chemotherapy or hormone therapy. ...Read more

Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

Is breast augmentation with stem cells by ddr. Heinrich effective?

Is breast augmentation with stem cells by ddr. Heinrich effective?

Unproven, and . . .: It would be surgical tourism since this doctor practices in vienna. Though stem cells are now available, and fat grafting to the breast is possible and controversial (results no bigger than 1 cup size, some dead fat causes calcifications and can interfere with cancer detection or mimic cancer on mammogram), this is far from mainstream. See abps-certified plastic surgeon and get implants! please! ...Read more

Would introducing mutated cells right next to cancer cells reverse the production of cancer cells?

Would introducing mutated cells right next to cancer cells reverse the production of cancer cells?

No: Cancer cells arise in a milieu of normal cells and have a growth advantage over them. I appreciate your idea, but it would be like putting a corrupted computer disk in with healthy ones in the hope of restoring its data. ...Read more

What is stem cell breast augmentation?

What is stem cell breast augmentation?

Fat Transfer: "stem cell" breast augmentation is really no more than fat transfer to the breast. There can be stem cells that are harvested along with the fat, but the majority is still fat. Some of this fat goes away after the injection, but that also means that some survives permanently. ...Read more

How to slow down the growth of cancer cells? (for last stage cancer patient, cancer cells at liver, lung and pelvis. Most critical is liver.)

How to slow down the growth of cancer cells? (for last stage cancer patient, cancer cells at liver, lung and pelvis. Most critical is liver.)

Your Oncologist can: This is a broad question. There are many anticancer drugs that are used to slow cancer cell growth. But they vary in their effectiveness depending on which organ is the source of cancer. Not knowing the details of the history i can not be any more specific. Please pose this question to the treating oncologist. ...Read more

Hi, What chances of cancer by doing Autologous Adipose derived stem cell treatment.Pls help.thanks?

Hi, What chances of cancer by doing Autologous Adipose  derived stem cell treatment.Pls help.thanks?

Not much: There isnt much but this depends on the context of why there is the transplant. It is used either in cancer http://www.wjgnet.com/1948-9366/full/v8/i2/161.htm or reconstructive surgery. In someone without cancer, they dont even do studies to evaluate risk since the risk is assumed zero. ...Read more

Mesothelioma biopsy says 'portions of fibrous tissue infiltrated by malignant cells forming nests. tumor cells +'ve for CK7 and calretinin. prognosis?

Mesothelioma biopsy says 'portions of fibrous tissue infiltrated by malignant cells forming nests. tumor cells +'ve for CK7 and calretinin. prognosis?

Marker not prognosis: CK7 and calretinin are used to verify that the tumor is mesothelial in origin (versus adenocarcinoma of the lung). It does not provide information about prognosis. Factors associated with pleural mesothelioma prognosis include: functional status, blood counts, histology (epithelial best vs fibrosarcomatous poorest), and tumor size (degree of involvement of pleural cavity). Several new trials. ...Read more

DCIS, left breast, biopsy itself removed high grade cancer cells, lumpectomy path 100% cancer free. Radiation necessary? What about proton therapy?

It depends: It may depend on your age. Radiotherapy to your involved breast may be required as it is the standard of care. Ask your doctor and let us know what advice you receive. Tamoxifen is another medication recommended after completion of Radiotherapy. ...Read more

DCIS calcifications ,biopsy itself removed all bad cells, lumpectomy pathology that followed 100% cancer free, radiation to aggressive?44 yr old.

DCIS calcifications ,biopsy itself removed all bad cells, lumpectomy pathology that followed  100%  cancer free, radiation to aggressive?44 yr old.

Depends: Two important other pieces of information are what the "grade" of the DCIS was which implies how aggressive it might be, and how much normal tissue was between the edge of what was removed and the DCIS. Both of these are taken into consideration when evaluating the role of radiation therapy for DCIS. Talk to your oncologist, your surgeon, and your radiation oncologist for more details. ...Read more

Does lung cancer surgery stimulate the remaining cancer cells to grow faster?

Does lung cancer surgery stimulate the remaining cancer cells to grow faster?

No.: The purpose of th surgery is to remove all the cancer. The myth that "the air causes it to grow" is false. The truth is cancer cells grow very well with or without surgery if they are hiding in nodes or far off places. This the proof that additional chemotherapy works in more advanced stage, and perhaps of some help in stage ii (+hilar nodes). ...Read more

If one has slow-growing metastatic breast cancer will the anti-cancer drugs make the cancer more aggressive?

If one has slow-growing metastatic breast cancer will the anti-cancer drugs make the cancer more aggressive?

Treatment: Does not alter biologic behavior. Mets are never good. Some argue to re-biopsy to recheck re-ceptors (er, pr her-2-neu): the cells that metastasize may be different from those at outset. Best gauge is time from DX to relapse for "slow". Bony only and er+ usually fit this pattern. Cytotoxic chemo does not change growth or met potential, but cancers themselves can mutate to more aggressive type. ...Read more

Breast Carcinoma (Definition)

Most breast cancers are carcinomas. This is a type of breast cancer. These cancers start in the cells that line organs and tissues. In fact, breast cancers are often a type of carcinoma called adenocarcinoma, which starts in cells that make glands (glandular tissue). Breast adenocarcinomas start in the ducts (the milk ducts) or ...Read more
