Is breast cancer infectious?

Not likely in any feasible method. The best way to put it is that it would be rather difficult to become infected by another individual with cancer. There is a phenomenon called metastasis. Only malignant tumor cells and infections have the established capacity to metastasize. Essentially what occurs is that cancer cells can "break away", "leak", or "spill" from a primary tumor, enter lymphatic and blood vessels, circulate through the bloodstream, and settle down to grow within normal tissues elsewhere in the body. When tumor cells metastasize, the new tumor is called a secondary or metastatic tumor, and its cells are like those in the original tumor. This means, for example, that, if breast cancer metastasizes to the lungs, the secondary tumor is made up of abnormal breast cells, not of abnormal lung cells. The tumor in the lung is then called metastatic breast cancer, not lung cancer. Although metastasis only refers to within an individual (i.e. infectious spread of cancer cells within their own body), it is completely conceivable that by taking up the metastatic cancerous cells into a syringe and injecting them into another immuno-compromised individual, that cancer can be spread to that individual. Although this is highly unlikely, it could be spread by shared needles.


How are tumor cells different from normal cells?

Cell division is not regulated in tumor cells.


What is the medical term meaning compression of surrounding cells by the tumor cells?

The medical term for compression of surrounding cells by tumor cells is "mass effect." This occurs when a tumor grows and displaces nearby tissues or organs, causing them to become compressed or distorted. It can lead to various symptoms depending on the location and size of the tumor.


How do maligant tumor cells differ to benige tumor cells?

Malignant tumor cells are cancerous, tend to grow rapidly, spread to other parts of the body, and can be life-threatening. Benign tumor cells are non-cancerous, grow slowly, do not invade nearby tissues, and are typically not life-threatening.


What are disseminated tumor cells?

Disseminated tumor cells are cancer cells that have detached from the primary tumor and spread through the bloodstream or lymphatic system to other parts of the body. These cells can potentially form new tumors, leading to the progression of cancer in different organs. Detection of disseminated tumor cells in the blood or bone marrow is a negative prognostic factor for cancer patients.

What does malignant neoplasm progression mean?

Malignant (very virulent or infectious) Neoplasm (abnormal gorwth of cells). It is sometimes defined as cancer. Technically, Malignant Neoplastic Progession is the abnormal and uncontrolled growth of cells or tissue which eventually forms a tumor.

Can brain tumor cells transit through blood vessels?

Some can, not all. If the tumor contains cells that can it will metastasize.
