Why is malignant melanoma so resistant to chemotherapy?
GaleEncyofMedicine
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.

Is chemotherapy and antibiotics the same?
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.
Is a malignant tumor cancerous?
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.
