Leukemia is not just a kind of blood cancer which occurs in children; it can affect people of all ages. There are some early warning signs of leukemia that you shouldn’t ignore at any cost and rush to a doctor whenever required. In the case of adults, it is diagnosed in people aged 65 to 74.

• Night sweats
  Night sweats are one of the early warning signs of leukemia. You start to sweat profusely at night, although the temperature of the room is normal. This is because leukemia makes you vulnerable to infections. After all, your body does not produce enough immune cells. In an instance of infection, the temperature of your body will rise automatically, causing night sweats and fever. 
• Shortness of breath
  Leukemia has many side effects, such as shortness of breath. This occurs when you are on the verge of T-cell acute lymphocytic leukemia. In this kind of leukemia, the cells cluster around the thymus gland. This can cause severe chest pain and even difficulty breathing. If the same is accompanied by coughing, wheezing, or feeling pain while breathing, you should immediately seek medical attention. 
• Loss of appetite
  Loss of appetite is again one of the early warning signs of leukemia. This occurs because the buildup of leukemia cells causes the spleen to enlarge, which subsequently presses against the stomach. In this condition, a person feels as though he is full. As a result, the person will consume a lesser amount of food than normal.
• Pain in bones and joints
  Leukemia may lead to acute pain in both joints and bones. The pain occurs as a result of bone marrow being full and overcrowded by cancer cells. These cancerous cells may form a mass either in the joints or near the spinal cord nerves. The pain may either be very sharp or dull, depending on the area. It mostly affects the long bones of arms and legs.
• Weight loss that cannot be explained
  Leukemia may also lead to weight loss, which sometimes cannot be explained. There are rapidly dividing cancer cells use a huge amount of energy that would otherwise be used to store fat. Leukemia may even produce cells that may affect the metabolism of the body. This means that the body will not be as efficient or fast in breaking food as in normal circumstances.
• Tiny red spots
  This is a common early symptoms of leukemia is the presence of tiny red spots on the skin. These are also referred to as petechiae. The tiny red spots or petechiae are caused by capillaries those tiny broken blood vessels under the skin. These are moreover caused by platelets which are responsible for a blood clot.

The signs and symptoms of leukemia may not be very specific and often are very vague. They may even go unnoticed when blood tests for other conditions are conducted. If the signs like the ones mentioned above persist, do not delay your trip to your doctor.
