In brief: Uncontrolled growth

Cancer or malignancy, refers to uncontrolled growth of cells, invasion and destruction of normal tissues by these cells and spread to distant organs with damage to those organs.

Your follow-up question is more complicated than can be addressed in this forum. Treatments of cancer include chemotherapy with drug, radiation and surgery. Treatment of epilepsy depends on the type of epilepsy and in part by trial and error with different drugs. Please see a neurologist for care.

In brief: Cell Immortality

Every organ in the body is made up of microscopic cells, which normally divide by a process called mitosis.
Trillions of bits of genetic material (dna, which makes up genes) get replicated each time this happens. Errors happen, but they're either fixed, or are just no big deal. Every once in a while, though, the error happens in an important gene that leads to unchecked cell division and cancer.

In brief: Unstable genes

Cancer is the price that we pay for being multicellular organisms produced in the setting of natural selection.
Genes mutate in our bodies, and sometimes enough mutations accumulate in a line of cells to cause the genome itself to become destabilized -- this is cancer. Thankfully, there are things you can do to avoid some of the common cancers or find them early for removal.

You can avoid a great deal of the myriad of cancers simply by not smoking and not drinking.

In brief: Forever growing cell

Cancer starts when normal cells get damaged and keep growing, forming a lump and sometimes moving to other parts of the body.
Normal cells grow and divide at different times in life, but then stop. Cancer cells never stop. They don't have an "off"switch. So they make more cells that also keep growing. Treatment removes the cells (surgery) and kills growing cells (chemo).

In brief: Unregulated growth

Cancer by definition is the growth in size and number in an unregulated manner of a cell line that has developed a mutation.
The mutation is passed through the offspring which accumulate more and more mutations. The defining factor is that the cells act immortal as compared to normal cells that have a programmed lifespan. They also do not respect normal anatomic boundaries and tend to metastasize.

In brief: Good question

Cancer is a term used to describe a whole range of diseases in which one of your body's cells, or group of cells, undergo a change in genetic background that allows the cell(s) to live and divide regardless of the normal cues that would tell them to stop.
This proliferation of careless cells hurts the local environment or that which it spreads to.

In brief: Abnormal growth

Body has capacity to control its growth, maintain cells normal structure & function , have a purpose, will co ordinate with other cells of body, stays with in the confinements like a well trained army, cancer cell does exactly opposite, abnormal cell no control invade and spread to other tissue and cancer cell has no purpose in the body.

In brief: Bad cell growth

Our bodies' cells, that make up our organs and blood and so on, normally have a very tightly regulated growth and life cycles.
When these processes go awry, there can be cell growth that gets out of hand, causing harmful effects like disruption of normal functions or structures, production or overproduction of certain body chemicals, or simply using too much energy.
