Beta-thalassemia major is a hereditary disorder that usually causes severe anaemia. This mutation/disorder eventually leads to death if untreated especially during in the first two years of infancy. The treatment usually involves the transfusion of blood to clear the phenotypic blockage caused by the mutation. However, it requires both alleles to have the thalessemia mutation for a patient to be said to have beta-thalassemia major. Hence, <u>it is </u><u>not true</u><u> that it involves just the x allele and thus affects males more often than females</u>.

Human papillomavirus (HPV), low socioeconomic level, smoking, marriage before the age of 18 years, young age at first coitus, several sexual partners, multiple sexual partners of spouse, and multiple childbirths are all established risk factors for developing cervical cancer. Because of hormonal changes or a compromised immune system, pregnant women may be more exposed to HPV infection or cancer.
Age may also play a role: Women who have their first child before the age of 20 are at a higher risk of cancer than those who wait until after the age of 25. Even if a person waits until marriage to engage in sexual activity or only has one partner.

The human organ in charge of detoxifying the blood, in addition to a variety of other functions, is the liver.
The liver is the largest solid internal organ of the human body. It is located in the abdominal region. To be precise in the upper right-hand side of the abdomen, just below the diaphragm. The liver has a variety of functions including:
- Enzymatic functions
- Production and excretion of bile
- Excretion of substances (eg hormones)
- Storage of glycogen and nutrients
- Detoxification of blood
among a few others.
The liver acts as the primary filter for the body's blood. It filters out toxins, breaks down chemicals through enzymatic processes, and removes alcohol from the blood. These processes create waste products known as urea and bile, which are excreted by the liver to be removed from the body by other organs.
