Being sick is one of the truly most horrible feeling that a person could experience. This is even worse for people who suffer from an incurable disease. One such disease is cancer. It has been impossible to cure because the cells change form as they continue spreading. They spread by the process of metastasis. Discussed below is 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.
You may wonder how the disease spreads. Once it is rooted in a primary point it takes a while and then starts spreading. It does not spread immediately because the healthy cells are protected by the immune system. The growth cells, therefore, create a force of adhesion different from the normal cells to make their movement a lot easier. They do not float, they actually crawl.
Of course, the idea of growth spreading to different parts of the body is disturbing. However, it does not actually happen as easily as you would think. Different kinds of growth have different chances of actually spreading to other parts. They evaluate each kind and treat the patients accordingly. The further along in stages the growth is, the higher the chances of spreading.
For tumor cells, they have two main ways in which they can move around. They can use the blood vessels going to the tumor or the lymphatic system. The lymphatic system is easier as they go on to form lymph nodes that are taken out and studied to determine the level of tumor after surgery. The bloodstream is a tough place for a tumor cell and chances of survival are very low.
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.
The tumor cells may face a lot of hostility in the bloodstream but may end up in a completely new organ. They then have to create an environment that allows them to grow. If the cells in the organ do cooperate, then there will be the growth of a secondary tumor. This will be very different from the primary tumor which is what makes it hard to treat cancer.
When tumor manifests itself in the form of a secondary tumor, treating it becomes really difficult. This is because the primary and secondary tumors differ and therefore they cannot be treated the same way. The best way to handle tumor is to remove a primary tumor before tumor has spread to other parts of the body.
