8. Anemia

Anemia is a condition that is characterized by a lack of hemoglobin – or more commonly known as red blood cells – in the blood. Whenever you are battling a disease and are low on red blood cells count, your kidney indicates your body to start producing them. However, a tumor in kidney affects this process.

The effects of red blood cells mean a constant feeling of lethargy. You’d feel tired while doing the most basic tasks such as cleaning the room, your skin will start to look pale and you’d feel unusually week.

Anemia is caused by many other serious diseases such as HIV/AIDS, rheumatoid arthritis, Crohn’s disease and Dengue Fever – it is a condition that shouldn’t be taken lightly.

Needless to say, if you are showing any of the symptoms rush to the doctor!
