Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. [3] [4] Cancer can be difficult to diagnose because its signs and symptoms are often nonspecific, meaning they may be general phenomena that do not point directly to a specific disease process.
Males with pure embryonal carcinoma tend to have a normal amount of the protein alpha-fetoprotein in the fluid component of their blood. The finding of elevated amounts of alpha-fetoprotein is more suggestive of a mixed germ cell tumour, with the alpha-fetoprotein being released by the yolk sac tumour component.
The central role of DNA damage and epigenetic defects in DNA repair genes in carcinogenesis. DNA damage is considered to be the primary cause of cancer. [17] More than 60,000 new naturally-occurring instances of DNA damage arise, on average, per human cell, per day, due to endogenous cellular processes (see article DNA damage (naturally occurring)).
How to tell your children you have cancer ... on the phone a lot or at doctor's appointments and it will be weird for a bit' so kids understand the change in their natural rhythm," says Ziegler ...
Due to the poor quality of most studies of complementary and alternative medicine in the treatment of cancer pain, it is not possible to recommend integration of these therapies into the management of cancer pain. There is weak evidence for a modest benefit from hypnosis; studies of massage therapy produced mixed results and none found pain ...
Because stem cells have a natural ability to migrate and also play a key role in cancer development, it has been proposed that a cancer of unknown primary site may form when deregulated, premalignant or cancerous stem cells migrate away from their natural tissue and give rise to a cancer in the new site before or without generating a tumor in ...
According to a recent study, baby teeth contain an abundance of stem cells, a very special type of cell that can potentially grow replacement tissue in the body and cure a number of diseases.
The cells in tubular adenomas, like most tumors that frequently progress to cancer, show certain abnormalities of cell maturation and appearance collectively known as dysplasia. These cellular abnormalities are not seen in benign tumors that rarely or never turn cancerous, but are seen in other pre-cancerous tissue abnormalities which do not ...
