General Information On Cancer Metastasis Research

By Ruth Hayes

Doctors have done their best to come up with as many vaccines and cures for diseases as possible to prevent further affecting of the human tissues. They even came up with antiretroviral drugs to help manage the HIV/AIDS epidemic. However, although they have tried, they are yet to find a way to deal with cancer without drastic repercussions. The article below elaborates more on cancer metastasis research.

Cancer is one of the most feared diseases today. This is because it is really hard to control and can spread at very high speeds. However, it can be solvable if detected in the early stages. This can be taken care of by surgery or even radiation therapy. Cancer patients are at the risk of more illnesses and even death when the disease spreads.

Although it may tough for growth to spread it still does. The growth cells have to put in more effort in order to affect the body cells. There are protective barriers for the normal cells which the growth cells have to bypass. They ensure that their adhesion is different from that of other cells in order to move in an easier way.

A very small percentage of growth cells, actually 0.01%, can actually be able to facilitate metastasis. Therefore, every kind of tumor is examined for their ability to spread. The affected person is thereafter given medication depending on the likeliness of it spreading. One thing is for sure, the more advanced the tumor stage is, the higher the chances of it spreading.

Metastatic growth mainly spreads in one of two ways. Through blood vessels or through lymphatic vessels. Lymphatic vessels are those that drain excess fluids to nearby lymph glands. The easier option is the lymphatic vessels. This is why during surgery you will find lymphatic nodes being removed and used to examine the stage of growth.

In some cases, the tumor cells go on to align themselves with the cells found in the lining of the blood vessels. These cells are known as endothelial and can contract thus leaving spaces for the tumor cells. They are also unable to detect the invasion of tumor cells as the cells may disguise themselves as lymphatic cells.

When the cells are detached from the primary tumor, the chances of survival may not be very high. However, they may find that they have landed in a different organ. If the organ does provide favorable conditions for the growth of a new tumor, the cells will multiply. This tumor is known as a secondary tumor and is definitely different from the primary tumor.

As above mentioned, the change in the cell structure causes difficulty in tumor treatment. A treatment that may work on the primary tumor may not have any effect on the secondary tumor. Therefore, the only way to treat tumor that has not spread is by removing the primary tumor. For metastatic tumor, it is best to consult a professional.
