Cancer is a broad group of various
diseases in that some normal cells are mutated so that they do not undergo
normal programmed cell death (apoptosis) and, instead, grow/divide
uncontrollably. If cancer cells grow in
a solid tissue, these cancer cells together are broadly referred to as a
tumor. Non-solid tumors include
leukemia, lymphoma, and multiple myeloma.
Currently, there are over 200 known
cancers that afflict humans; all of which involve uncontrolled cell
growth. Cancer cells divide and grow
uncontrollably, forming malignant tumors, and invade nearby parts of the
body. Cancer may also spread to more
distant parts of the body through the lymphatic system or bloodstream and
becomes metastatic, which means cancer cells have spread to another
non-adjacent organ or tissue.
