What are the different types of pituitary tumor?

The pituitary tumor, or pituitary gland, is a solid mass of abnormally growing cells placed in the pituitary gland at the bottom of the brain. Their sizes are usually in smaller ranges, so the pituitary tumors are difficult to detect and can therefore continue to be undiagnosed until critical symptoms are achieved. The pituitary gland is not technically part of the brain and has a different composition from brain tissues, so that pituitary tumors are not considered brain tumors. Different types of pituitary tumors can be classified into different groupings such as microadenomas or macroadenomas and functional tumors or non -functional tumors. They include adrenocorticotrophic tumors, gonadotrophic tumors, lactotrophic tumors, somatotrophic tumors and thyrotrophic tumors.

In terms of size, the pituitary tumor is called microadenoma if it is less than 0.4 inches (10 mm) or macroadenoma if greater than 0.4 inches (10 mm). The pituitary tumor is also classified as functioning if the tumor produces additional hormones oras non -functional if it does not create any hormones. Functional pituitary tumors are further categorized depending on the type of hormones that exclude.

Adrenocorticotrophic tumors are those that produce adrenocorticotropic hormone (ACTH), which oversees the adrenal gland and produces regulated amounts of cortisol and adrenaline. Gonadotrophic tumors secrete the luteinization hormone (LH) and follicles stimulating hormone (FSH), using menstruation in women and sperm production in men. Lactotrophic tumors, also known as prolactinomas, excessive prolactin, hormone responsible for breast milk production. Somatotrophic tumors produce excessive growth hormones, which can lead to abnormal swelling of the body parts such as limbs, skull and hands. Tyrotrophic tumors exclude thyroid stimulation (TSH), which stimulates the thyroid gland to secrete hormones for metabolism and growth.

Tumors of pituitary gland produceExcessive and unfounded hormone levels, so they can bring some diseases or irreversible conditions such as gigantism, infertility, impotence and Cushing's disease. The pituitary tumor can be treated in several ways. The most common treatment is surgery to completely eliminate the pituitary tumor. In some cases, when tumors are found to be too small to be on it, treatment, treatment is an alternative treatment or patients can wait for the tumor to increase.

If radiation and surgical treatment cannot be performed, drugs can help reduce the size of the tumor or remove or regulate the hormonal pituitary production. Persistent symptoms may indicate the presence of pituitary tumor such as headaches, nausea, blurred or loss of vision, increased or reduced appetite, early or late puberty and Growth, irregular menstrual cycles and unexplained mood fluctuations. Consultation with a doctor is best to experience combined symptoms.
