All tissues need to be continually bathed in nutrients. They get these nutrients from the continuous flow of blood through blood vessels. This is why blood vessels run throughout our entire bodies. An aggressive tumor can take advantage of this fact.Tumors can actually induce new blood vessels to form within them so that they can receive nutrients. This process is called angiogenesis. Make no mistake, it's eerie. The tumor cells actually stimulate the cells lining nearby blood vessels to grow toward them. They achieve this by sending out a signal. This signal stimulates the cells within the nearest blood vessels to divide 20 to 2000 times faster than usual. Due to their unnaturally quick growth, the new blood vessels are usually not

The thyroid gland is one of the most important parts of our body. If something were to happen with gland one this is for certain: we must found out as quick as possible.This is the reason why today there are lots of tests that can help detect problems with the thyroid, like tumors or masses. Of course some test are more certain than others.Many may thing that most of the tests performed are a waste of time and especially money. Some may argue with this. That being said, I'll present you some of the most common tests that are available.One of the most frequently used tests in many cases not only to determine a thyroid tumor is the blood test. If the

There is a large body of evidence proving that all the cells within a tumor mass are derived from a single cell. Imagine; one damaged cell can lead to a life-threatening tumor. The magnitude of the true meaning behind this is difficult to grasp because it is an extremely shocking and frightening revelation.Even though all the cells within a tumor mass may be derived from a single cell, this does not mean that all the cells in a tumor are genetically identical like you might expect. Tumor cells are more unstable than normal cells, meaning they mutate at a much higher rate and they repair themselves much less effectively. Therefore, the cells within a tumor are different even from one another.Fortunately, the

There are two adrenal glands, one on top of each kidney toward the back. Tumors of the adrenal glands are rare. However, when present, they can cause many problems by excess secretion of certain adrenal-produced hormones. One type of tumor of the adrenal glands is called a pheochromocytoma.Adrenocortical carcinoma is a rare malignant neoplasm of adrenal glands, which most often presents without any hormonal symptoms. The most common clinical presentation of patients with hormone-secreting adrenocortical carcinoma is that of CushingÕs syndrome. Other hormonal hypersecretion syndromes associated with adrenocortical carcinoma include virilization (from androgen-producing tumors), feminization (estrogen-producing tumors), and hyperaldosteronism. Multiple hormones may be produced by a single tumor, causing a mixed clinical picture.Tumors of the adrenal glands are rare. However, when present

When you are diagnosed with a meningioma or you are told that a loved one has been diagnosed with this medical condition it strikes terror into your heart and there are so many different questions, concerns and fears, it is literally an emotional roller coaster of feelings especially when you don't know much about the condition.Nothing conclusive has been found out about this type of brain tumor. The survival rate for those with meningioma is high, but the very idea of knowing the medical condition exists can be devastating. Offering support to someone that has this type of brain tumor can be difficult when you feel in such turmoil yourself but being with them through the various tests and treatments can ease

/>Tropical fish are like other species in many respects, and that includes the fact that they have diseases or disorders that may resemble those of other animals, but are specific to the fish themselves. One good example is tumors. Just as humans, cats or dogs may get cancer or other types of tumors, so can tropical fish. The main difference is that treatment in fish is nearly impossible, depending on the type and location of the mass. Not only are they difficult to handle where a human can have clear visual access to them, but such things as surgery are basically out of the question. Tumors generally show themselves as a lump under or on the skin of fish. These are a distinct bump
