- Reduce in weight
- Bone pain
- Breathing difficulty
- Large amount of sweating at night
Causes of Leukemia – Now the scientists did not know the exact cause of leukemia but it may be develop from the combination of environmental and genetic factors.
Classification of Leukemia – The classification of leukemia was based on the speed of progression and the type of cells involved.
- Acute Leukemia – It is one of the most common pediatric cancers. In this type of Leukemia, the cells are rapidly dividing and the disease progresses quickly. If you are suffering this type of cancer then feel sick within weeks of the leukemia cells forming.

- Other types of cancer – There are some other types of leukemia exist including myelodysplastic syndromes, myeloproliferative disorders and hairy cell leukemia.
Risk factors – There are some of the factors which increases the risk of developing several types of leukemia which are as given below –
- Genetic orders – Some of the genetic abnormalities plays an important role in the development of leukemia. There are several genetic disorders increases the risk of leukemia such as down syndrome.
- Smoking – Smoking tobacco cigarettes may be responsible for increasing the risk of acute myelogenous leukemia
- Earlier cancer treatment – If you have had certain types of radiation therapy and chemotherapy for the treatment of other cancer then it increases the risk of some types of leukemia.
- Chemicals – There are some of the chemicals including benzene is present in gasoline which is used by the chemical industry increases the risk of some types of leukemia.
