Wh?t ?? cancer, h?w d??? ?t ?t?rt ?nd h?w d??? ?t spread?

Cancer ?? a group ?f many related diseases th?t b?g?n ?n cells, th? body's basic building blocks. T? understand cancer, ?t ?? helpful t? know wh?t happens wh?n normal cells become cancerous.

Th? body ?? m?d? up ?f many types ?f cells. Normally, cells grow ?nd divide t? produce more cells, ?? th?? ?r? needed t? keep th? body healthy.

Sometimes, th?? orderly process goes wr?ng. N?w cells form wh?n th? body d??? n?t need th?m, ?nd ?ld cells d? n?t die wh?n th?? ?h??ld. Th??? extra cells m?? form a mass ?f tissue called a growth ?r tumor. H?w???r, n?t ?ll tumors ?r? cancerous. Tumors ??n b? benign ?r malignant.

Benign tumors ?r? n?t cancer. Th?? ??n ?ft?n b? removed ?nd, ?n m??t cases, th?? d? n?t come back. Cells ?n benign tumors d? n?t spread t? ?th?r ??rt? ?f th? body. M??t ?m??rt?nt, benign tumors ?r? rarely a threat t? life.

Malignant tumors ?r? cancer. Cells ?n malignant tumors ?r? abnormal ?nd divide without control ?r order. Cancer cells invade ?nd d??tr?? th? tissue around th?m. Cancer cells ??n ?l?? br??k away fr?m a malignant tumor ?nd enter th? bloodstream ?r lymphatic system, wh??h ?? h?w th?? ??n spread t? ?th?r ??rt? ?f th? body.

Blood vessels include a network ?f arteries, capillaries ?nd veins through wh??h th? blood circulates ?n th? body. Th? lymphatic system carries lymph ?nd white blood cells through lymphatic vessels (thin tubes) t? ?ll th? tissues ?f th? body.

B? moving through th? bloodstream ?r lymphatic system, cancer ??n spread fr?m th? original cancer site t? form n?w tumors ?n ?th?r organs. Th? spread ?f cancer ?? called metastasis. Th?nk ?f th?? ?? th? highway system, ?nd th?nk h?w easy ?t ?? t? g?t around th?? country b? taking highways.

Women: Breast, colorectal ?nd lung cancer

Men: Prostate, colorectal ?nd lung cancer

H?w d? cancers differ?

Th?r? ?r? over 200 types ?f cancer. Th? National Cancer Institute lists several general categories; th?? list ?? n?t ?ll-inclusive:

• Carcinoma: Cancer th?t b?g?n? ?n th? skin ?r ?n tissues th?t line ?r cover internal organs, such ?? skin, lung, colon, pancreatic, ovarian cancers, epithelial, squamous ?nd basal cell carcinomas, melanomas, papillomas ?nd adenomas.
• Sarcoma: Cancer th?t b?g?n? ?n bone, cartilage, f?t, muscle, blood vessels ?r ?th?r connective ?r supportive tissue, such ?? bone: soft-tissue cancers, osteosarcoma, liposarcoma, angiosarcoma, rhabdosarcoma ?nd fibrosarcoma.
• Leukemia: Cancer th?t ?t?rt? ?n blood-forming tissue, such ?? th? bone marrow, ?nd causes large numbers ?f abnormal blood cells t? b? produced ?nd enter th? blood stream, such ?? leukemia, lymphoblastic leukemia (ALL ?nd CLL), myelogenous leukemia (AML ?nd CML), T-cell leukemia ?nd hairy-cell leukemia.
• Lymphoma ?nd myeloma: Cancers th?t b?g?n ?n th? cells ?f th? immune system, such ?? lymphoma, T-cell lymphomas, B-cell lymphomas, Hodgkin lymphomas, non-Hodgkin lymphoma ?nd lymphoproliferative lymphomas.
• Central nervous system cancers: Cancers th?t b?g?n ?n th? tissues ?f th? brain ?nd spinal cord, such ?? brain ?nd spinal cord tumors, gliomas, meningiomas, pituitary adenomas, primary CNS lymphomas ?nd primitive neuroectodermal tumors.

N?t included ?n th? above types listed ?r? metastatic cancers b?????? th??? cells usually arise fr?m a cell type listed above. Th? major d?ff?r?n?? fr?m th? above types ?? th?t th??? cells ?r? now present ?n a tissue fr?m wh??h th? cancer cells d?d n?t originally develop.

H?w ?? ?t treated?

Cancer treatment ??n include surgery, radiation therapy, chemotherapy, hormone therapy ?nd biological therapy. Th??? treatments ??n b? given alone ?r ?n a number ?f combinations.

Determination ?f wh??h treatment ?? best f?r ??? depends ?n th? type ?nd location ?f th? cancer, whether th? disease h?? spread, th? patient's age ?nd general health ?nd ?th?r factors.

B?????? treatment f?r cancer ??n ?l?? d?m?g? healthy cells ?nd tissues, ?t ?ft?n causes side effects. S?m? patients m?? worry th?t th? side effects ?f treatment ?r? worse th?n th? disease.

H?w???r, patients ?nd doctors generally discuss th? treatment options, weighing th? l?k?l? benefits ?f k?ll?ng cancer cells ?nd th? risks ?f possible side effects. Doctors ??n suggest ways t? reduce ?r eliminate problems th?t m?? occur during ?nd ?ft?r treatment.
