Cancer is a disorder of altered cell __________ and _________.
Malignant tumours are less well _____________ and have the
ability to break __________, enter the _______________ or
_______________ systems and form secondary malignant
tumours at other sites.
Compare and contrast benign tumours and malignant
tumours.
What is paraneoplastic syndrome?

Genetic disorders are inherited as autosomal dominant
disorders, in which each child has a 50 percent chance
of inheriting the disorder, or as autosomal recessive
disorders, in which each child has a 25 percent chance
of being affected, a 50 percent chance of being a
carrier, and a 25 percent chance of being unaffected.
2. Sex-linked disorders almost always associated with the
X chromosomes and are predominately recessive.
3. Chromosomal disorders reflect events that occur at the
time of meiosis and result from defective movement of
an entire chromosome of from breakage of a
chromosome with loss or translocation of genetic
material.

1. Single defective or mutant gene.
2. Lead to formation of an abnormal
protein or decreased production of a
gene product.
3. The disorder can result in a defective
enzyme, defects in receptor
proteins and their function or
mutations resulting in unusual
reactions to drugs.
