What type of diseases are caused by abnormal genes and lifestyle factors?

The type of diseases caused by abnormal genes and lifestyle factors is classified as non-infectious diseases. These diseases result from a variety of factors that are not directly transmitted from person to person, in contrast to infectious diseases, which are caused by pathogens and can spread through contact with infected individuals or surfaces. Non-infectious diseases can manifest due to genetic predispositions, environmental factors, and personal lifestyle choices, such as diet, exercise, and exposure to toxins. Conditions such as heart disease, diabetes, and certain cancer types fall within this category, highlighting the significant role both genetics and lifestyle play in the development of these diseases.
