One suggestion as of late 2003 is that the genes ordinarily responsible for apoptosis (cell self-destruction) do not function normally in melanomas.
No. But cancer may be treated, usually with chemotherapy (chemicals) or radiotherapy (radiation), and the idea is to control malignant cells so that they do not spread to other organs of the body.
It is not so much the total sun exposure that seems important, rather it is the history of sunburn, (especially if severe or at an early age), that correlates with the increased risk.
Well, honey, the type of skin cancer that occurs in melanocytes is melanoma. Those pesky melanocytes decide to go rogue and start multiplying like there's no tomorrow, leading to this serious form of skin cancer. So, slap on that sunscreen and keep those melanocytes in check!
No. It doesn't affect you like the flu does, so no need to worry.
Renal cell carcinoma is mostly resistant to radiation and chemotherapy, so the only practical treatment options are surgery and immunotherapy.
There is no specific amount of time for malignant tendencies to turn malignant. If they are going to become malignant, they will usually do so within months.
The tumor is malignant, which means cancerous, so I'll have to have it removed.
There is no any specific demarcation to say whether it is benign or malignant. We have WHO grading system which tells us that only cellular features of malignancy are present. But there is no metastasis so i would say that it is benign with malignant potential.
It appears there may have been a spelling error. Did you mean "glioma"? If so, a glioma is a type of tumor that originates in the brain or spinal cord and arises from the supportive tissue of the brain. Gliomas can be benign or malignant, and treatment usually involves a combination of surgery, radiation therapy, and chemotherapy.
No, they don't cause melanoma, which is a skin cancer. They may make you more sensitive to the sun, however, so be sure to use sunscreen. Reduce your time in the sun if you notice you sunburn more quickly.
Yes, a malignant tumor is cancerous. The term "malignant" is used in medical terminology to describe tumors or growths that are cancerous in nature. Malignant tumors are characterized by uncontrolled and abnormal cell growth, and they have the potential to invade nearby tissues and spread to other parts of the body through a process called metastasis. This ability to invade and metastasize distinguishes malignant tumors from benign tumors, which do not invade nearby tissues and are typically noncancerous.
Chemo and Radiation, in short actually mean CHEMOTHERAPY and RADIOTHERAPY respectively.Commonly Chemotherapy indicates the treatment of malignant diseases by using different natural or synthetic chemical compounds either by oral,topical or intravenous route.Mode of action of these agents are bit complicated but in short,they target the rapidly dividing tumor cells and destroy them sparing the normal ones.primarily the site of action is intra cellular nucleas where the chromosomes,containing DNA molecules,reside.few commonly used Chemotherapy agents are:CYCLOPHOSPHAMIDE,METHOTREXATE VINCRISTINE,VINBLASTINE,DOXORUBICIN etc.few agents areaalso used in non-malignant conditions also e.g.METHOTREXATE is also used to treat Rheumatoid Arthritis By the term Radiotherapy,generally the therapeutic appraoch by high frequency electro-magnetic waves,usually by gama-rays of any radioactive element is meant. By applying those radiation,the tumor cells are destroyed usually in malignant diseases with distant spread.Radiotherapy can be given to the patients from a machine(TELECOBALT,TELECESIUM etc),placing tiny pieces of radioactive agents in the body(BRACHYTHERAPY). In few occassions,radioactive agent are used in nonmalignant conditions as in GRAVES DISEASE where 131-iodine is used. As therapeutic practice,both the modalities are used to treat malignant condition with or without distant spread,either single or in combination when surgery shows no promise.
