Answer:

A) S-I and S-II both are true

Explanation:

In our body, normal cells show the property of contact inhibition, that is when cells come in contact with other cells, inhibition of their uncontrolled growth occurs. Cancer cells appear to have lost this property and they continue to divide giving rise to numerous masses of cells called tumors.

These tumors are of two types: Benign and malignant tumors. Benign tumors remain confined to their site of origin and normally do not spread to other parts of the body hence causing little damage.

Malignant tumors grow very rapidly and are a mass of proliferating cells called neoplastic or tumor cells. They invade and damage the surrounding tissues. They have the property of metastasis by which they reach distant sites of the body and start a new tumor there. These cancerous cells also compete with the normal cells for vital nutrients.

Cancer is caused due to physical, chemical or biological agents called carcinogens. Cancer can be detected by using many techniques such as radiography, MRI or CT. Immunotherapy, chemotherapy, surgery are some of the common methods for the treatment of cancer.
