Question

Give any two examples of non-infectious diseases.

Answer 1

Non-communicable diseases (NCD) are a group of diseases that are not transmissible directly from one infected person to a different healthy person.
NCDs could also be chronic or acute. Mostly NCDs are found to be non-infectious, however, there are some non-communicable infectious diseases as well (like parasitic diseases).

Complete answer: Two most common non-infectious diseases are:
CANCER: Cancer is the term given to a set of related diseases.

Altogether, there are several sorts of cancer, based on the location of the tumour formation.
A number of the body's cells begin to divide uncontrollably and spread into surrounding healthy tissues. Old cells don't die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor.
Cancer can take root in almost any part of the body, which is formed from the trillions of cells.

ASTHMA: Asthma is a condition of the respiratory tract which is characterized by the narrowing and swelling of the airways along with the production of extra mucus.

This will make breathing difficult and trigger coughing, a whistling sound (wheezing) once the person exhales, and shortness of breath.

Note: These diseases are not caused by pathogens.
Instead, they are likely to have caused such as lifestyle factors, environmental toxins, or gene mutations.
