Urgent, doctors :'( my mom has metastases liver cancer, lung and bone nearby left thigh found tumors. Just found out few days ago,  is stage 4. How?

This is too: Common. Some cancers are quiet until they infest other organs, and it is these organs working poorly or hurting that causes the cancer to be known. Some cancers can have life extended by treatment (prostate and breast), others can be treated to relieve symptoms. But for most, it means time to focus on comfort and symptom relief rather than rigorous treatment. ...Read more

Neoplasms (Definition)

"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more

How to differentiate primary tumor cells from cells of metastases?

How to differentiate primary tumor cells from cells of metastases?

Close exam: primary tumor cells are well defined, arising in the organ that initiates the lesion. A cancer of the breast when biopsied shows adenoca cells of breast origin. When metastatic to liver or lung, biopsy will show the same cells as the primary . If the lesion arises in the liver it is not metastatic in terms of cells seen but liver tumor cells or hepatoma. ...Read more

How would angiogenesis influence tumor growth and metastasis?

How would angiogenesis influence tumor growth and metastasis?

Fundamental!: All living things need a blood supply to deliver food, water, and get rid of waste. A circulating cancer cell needs to evade detection, get out of the blood vessel, and establish that blood supply: angiogenesis!. All these actors under molecular control, and likely normal during in utero development. Cut off the blood supply, choke the tumor. ...Read more

I know malignant tumors shows metastasis but benign tumor not. But there is an example of benign tumo?

Some do spread: By definition a benign tumor does not have the potential to spread. Distant spread has occurred when a lesion that is manipulated or curetted has shown signs of spread. This is really not metastasis. A report of benign metastasizing fibroma of the thumb was reported by keasby many years ago. Some benign sweat gland tumors of axilla have been shown to be present in axillary nodes, . ...Read more

Metastasis (Definition)

A cancer begins in an organ (say the breast). If it gets into the blood stream or the lymphatic stream the cells can travel to other parts of the body where, in the right environment, they may settle and grow. This development of tumor growth far away from the original site ...Read more
