Understanding and Recognizing Leukemia Symptoms

Leukemia is a sort of cancer of the blood and marrow. The disease is characterized through the overproducing of immature blood cells (stem cells) that aren’t able to fully develop and carry out the activities of normal blood cells.

Each type of mature blood cells has specific traits and roles inside the body. White blood cells or leukocytes have an important role in the immune system, contributing to overcome infections. White blood cells also help in healing flesh wounds and cuts. Red blood cells or erythrocytes contain hemoglobin, which has a great importance in transporting oxygen to the cells within the organism. Red blood cells are vital for the process of cell respiration, carrying oxygen to cells and removing carbon dioxide from them. Platelets have an important role in repairing damage at the level of blood vessels, accumulating to seal any cuts or tares.

Leukemia leads to the accumulation and crowding of diseased stem cells at the level of the bone marrow, which decreases the normal production of healthy blood cells. The lack of normal blood cells leads to the appearance of leukemia symptoms.  It is important to understand that despite the fact that leukemia causes an over production of white blood cells, these cells are immature and can’t substitute for normal blood cells. Due to this, the body is exposed to many forms of infection.

The most common leukemia symptoms are: anemia (insufficient number of red blood cells in the bloodstream), risks of bleeding (insufficient number of platelets in the bloodstream), nose bleeding, bleeding of the oral cavity, predisposition to bruising, high exposure to infections due to lack of white blood cells, improper healing.

Other leukemia symptoms may be fatigue, lack of concentration, poor psychical performance, fever, loss of appetite and weight loss.

In the case of chronic leukemia, which facilitates the accumulation of diseased blood cells in different places inside the body, the leukemia symptoms may be migraines, insomnia, decreased vision and hearing, loss of balance, faints and seizures. Some of these leukemia symptoms need immediate medical intervention, as they may lead to further complications.

Sometimes people with leukemia may have enlarged liver and spleen, causing abdominal swelling or enlarged lymph nodes. The body glands of the organism can also be affected by leukemia.

Leukemia symptoms have a non-specific character. This means that they can be misleading in establishing an appropriate diagnose, as they may also occur in the cases of other diseases. Medical professionals are the only persons able to distinguish leukemia from other illnesses with resembling symptoms. Proper diagnose is very important in order to quickly begin the administration of specific treatment. Blood analysis and careful body examinations can reveal the presence of leukemia. Leukemia is considered to have a high rate of mortality and although the disease can be overcome through treatment and therapy, it can cause death if its presence is not noticed in time. Therefore, prompt intervention is required for leukemia, regardless of its type.

Possible Leukemia Causes and Risk Factors

Leukemia is a disease that is considered to be life-threatening. It requires prompt intervention when discovered, in order to maximize the chances of recovering through specific treatment and therapy. Leukemia is basically a type of cancer of the bone marrow and blood, caused by inappropriate cellular activity. The disease can be of different forms, according to the types of blood cells that cause its development. Also, if leukemia is developing rapidly, it is called acute leukemia, while if the disease is developing slowly, it is referred to as chronic leukemia.

The direct leukemia causes are still unknown. In present, medical science isn’t able to establish the specific leukemia causes. However, a strong connection between certain genetic factors and the development of the disease has been revealed. Leukemia occurs on the background of genetic failure that causes the excessive production of incomplete, partially matured blood cells. Also, leukemia has a hereditary character, allowing the transmission of genetic predispositions to disease from one generation to another. Although many factors are known to contribute to the development of leukemia, they alone can’t be considered leukemia causes.

Despite the fact that statistics indicate a higher incidence of the disease in people that are exposed to some environmental factors of risk, leukemia doesn’t seem to be caused by neither of them in particular. Among the environmental factors that are thought to be leukemia causes, here are some of the most plausible ones:

- Smoking – smoking is thought to increase the chances of being affected by leukemia. Although statistics show that around 20 percent of acute leukemia cases are related to smoking, leukemia also occurs to people that don’t smoke and therefore it can’t be considered a leukemia cause on itself;

- Prolonged exposure to radiation – Radiation is considered to facilitate the development of leukemia. It is believed that exposure to X-rays can be a leukemia cause;

- Prolonged exposure to benzene – statistics reveal that this is a major factor of risk in some forms of leukemia, such as myelogenous leukemia;

- Chemotherapy and cancer treatment – previous cancer treatments and chemotherapy are known to facilitate the occurrence and development of leukemia and can be considered plausible leukemia causes. Within a few years from the completion of chemotherapy and other treatments for certain forms of cancer, most people can develop leukemia.

Among the genetic factors that are considered to be leukemia causes, the following ones are thought to be the most important:

- chromosome abnormalities – some rare genetic syndromes are known to contribute to leukemia causes;

- Immune system genetic problems - a weak immune system is very likely to facilitate the occurrence of leukemia and therefore can be considered a leukemia cause;

- Down syndrome – children born with this syndrome have a very high risk of developing acute leukemia.

The list of possible leukemia causes can continue further, but these are the most common factors that are considered to be interrelated with leukemia. While some of them can be prevented, others reside within the genes and in present can’t be corrected. In future, however, thanks to medical advance, we will probably be able to prevent leukemia and other forms of cancer.
