nutrients

5.  In ancient Egypt in 1500 BC world's oldest recorded case of

 Treated with cauterization (destroyed tissue with a hot
instrument called "the fire drill." )
 At that time considered that there was no treatment for the
disease only palliative treatment.

6.  It is a genetic disease
 Caused by changes to genes because
 Error occur in cell division
 Damage DNA
 Inherited from parents.

7.  It spread such ways
1. Spread from the place where it first formed to another place
in the body is called metastatic cancer.
2. The process by which cancer cells spread to other parts of

form solid tumors.
 Lymphoma
 It begins in lymphocytes (t cells or b cells).

13.  Multiple myeloma
