Answer :
Inheritance of certain genes increases the risk of getting certain cancers; thus, it can be said that predisposition to these cancers is inherited.
What is cancer?
Cancer is a condition when a few of the body's cells grow out of control and spread to other bodily regions.
In the millions of cells that make up the human body, cancer can develop practically anywhere. Human cells often divide (via a process known as cell growth and multiplication) to create new cells as the body requires them. New cells replace old ones when they die as a result of ageing or damage.
Occasionally, this systematic process fails, causing damaged or aberrant cells to proliferate when they shouldn't. Tumors, which are tissue masses, can develop from these cells. Tumors may or may not be malignant (benign).
Cancerous tumors can move to distant parts of the body to produce new tumors, invade neighboring tissues, or both (a process called metastasis). Malignant tumors are another name for cancerous tumors. Malignancies of the blood, including leukemias, seldom develop solid tumors although many other cancers do.
What are genes?
The fundamental structural and operational component of heredity is a gene. DNA is the component of genes. Some genes serve as blueprints for the synthesis of proteins. Many genes do not, however, code for proteins. A few hundred DNA bases to more than 2 million bases make up a gene in a human. Humans are thought to have between 20,000 and 25,000 genes, according to the Human Genome Project, an international research project that aimed to decipher the human genome's sequence and catalogue its genes.
