Risk Factors for Medulloblastoma

Medulloblastoma is a type of malignant tumor that develops within the lowermost region of your brain, more commonly known as the cerebellum. It is considered a tumor of the central nervous system (CNS). And much like other forms of cancer, it can metastasize. The most common area of metastasis is into the spinal cord, but it may also spread into other areas of the body. When the mass forms, it often causes you to experience a loss of balance, slowed speech, periodic headaches and a feeling of nausea. Mood or behavioral changes are also quite common. You can even suffer from fatigue, fluctuations in weight and trouble waking or writing. As with almost any disease or illness that can affect the body, there are certain risk factors linked to the development of medulloblastoma.

Age

• The most predominant risk factor for medulloblastoma is age. And with this form of cancer, it is more likely to develop at an earlier age, usually during childhood. According to the American Society of Clinical Oncology, the majority of medulloblastoma cases are seen under the age of eight. Of this, half develop within the first six years of a child's life.

Sex

• Another predominant risk factor for medulloblastoma is sex. This form of cancer is seen more often in boys than girls. But since the actual cause of the malignant tumor is unknown, the reason for the predominance in the male sex is still unknown.

Race

• Your race can also place you at a higher risk of developing a malignant tumor. Most cases of this form of cancer are seen within the white demographic. This doesn't mean that other races won't develop this condition; it just isn't as likely.

Genetics

• Though not as common as age, sex and race, your genetics can also contribute to your risk factors. In some cases of brain tumors, a family history is present, making the person more susceptible or prone to their development. However, just because a family member has suffered from a brain tumor doesn't mean you (or your child) will automatically develop a malignant mass. It simply puts you at a greater risk.

Recurrence

• With medulloblastoma, there is also a risk of recurrence. But this risk is based on certain factors, such as age, location, stage and success of initial treatment. When a child is younger (under the age of three), the tumor is located in another area of the brain other than the base, cancer wasn't entirely removed and it has spread to other areas of the body, the risk of recurrence is much greater.
