Do you know what the most prevalent types of brain tumours are?


There are over 130 different forms of brain and central nervous system tumours, ranging from benign to malignant, exceedingly rare to reasonably common. 

Metastatic

Metastatic brain tumours are the most frequent type of brain tumour in adults. They are classed as secondary brain tumours because they develop from cancer that began elsewhere in the body and migrated to the brain. The exact incidence rates are unknown; however, the American Brain Tumor Association believes that between 200,000 and 300,000 metastatic brain tumours are detected each year. Lung or breast cancer is the most common cause of metastatic malignancies. Larger metastatic tumours are frequently surgically excised (meaning removed), whereas smaller tumours may be treated with a gamma knife, a type of radiation therapy that focuses 200 tiny beams of radiation onto the tumorous area.

Meningioma

Because they grow in the meninges, which are the membranes that line the skull and spinal canal, these tumours are not really brain tumours. However, their development may have an impact on the brain, resulting in a variety of problems such as vision and hearing impairment, memory loss, and even convulsions. Meningioma cases surge with age, and the tumours grow slowly, thus symptoms may appear gradually over time. If the tumour begins to impair one's quality of life, doctors will either surgically remove it or treat it with radiation therapy. Chronic headaches are the most prevalent early indication of meningioma.

 Glioblastoma

Despite being the third most frequent type of brain tumour, glioblastoma is the most frequent primary brain tumour, meaning it begins in the brain. It's also the most dangerous. Every year, around 15,000 new cases of glioblastoma are identified, with average survival rates ranging from 11 to 15 months. To combat glioblastoma, a variety of treatment techniques, including surgical resection, radiation therapies, and chemotherapy, are frequently used.

Astrocytoma

These primary tumours begin in star-shaped cells called astrocytes, which are found in the cerebrum of the brain. The grade of astrocytoma tumours varies, indicating their level of malignancy and aggressiveness; some develop slowly (Grade II), while others develop more aggressively (Grade III). Surgery is always used to treat astrocytomas, and chemotherapy and radiation therapy are used on occasion.  According to the American Cancer Society, the survival rate for low-grade astrocytomas is around 68 per cent for patients aged 20 to 44, and drops to 44 per cent for individuals aged 45 to 54.

Persistent headaches are the most prevalent early symptom of a brain tumour. Having said that, headaches are a rather common occurrence in everyday life. There are various ways to distinguish a typical headache from one caused by a greater disease, such as a brain tumour.

Some warning indications would be if your headaches become more frequent and powerful over the course of a few days or weeks, and if your headaches became so severe that they woke you up while you were sleeping. If you have no history of persistent headaches and suddenly start getting these headaches, it is something to be concerned about.

Do you know what an acoustic neuroma is?

Image
  An acoustic neuroma is a noncancerous growth that appears on the eighth cranial nerve. The vestibulocochlear nerve, often known as the auditory nerve, connects the inner ear to the brain and is divided into two segments. One half is responsible for sound transmission, while the other aids in the transmission of balancing information from the inner ear to the brain Acoustic neuromas, also known as vestibular schwannomas or neurilemmomas, often grow slowly over time. Although they do not invade the brain, they can exert pressure on it as they grow. Larger tumours can strain on neighbouring cranial nerves that govern facial expression and sensory muscles. If tumors develop large enough to press on the brain stem or cerebellum, they can be deadly. Symptoms The first symptom is typically a gradual loss of hearing in one ear, which is frequently accompanied by ringing in the ear (tinnitus) or a sensation of fullness in the ear. Acoustic neuromas are less prevalent causes of abrupt hea

Do you know what vitamins are used for nerve regeneration?

                                 Do you know what vitamins are used for nerve regeneration? Neuropathy is a term that refers to a group of diseases that damage the nerves and can cause a variety of unpleasant and painful symptoms. Neuropathy is a common side effect of chemotherapy and a consequence of diabetes. Vitamin B complex or vitamin B12 has been proven to increase the number of Schwann cells, myelinated nerve fibres, and axon diameter, promoting myelinated nerve fibre regeneration and Schwann cell proliferation. Neuropathy is a type of nerve injury that is common in diabetics and as a side effect of chemotherapy . Supplements may help alleviate symptoms of neuropathy, in addition to lifestyle changes and conventional treatments. B-12, B-6, and other B-complex vitamins may also help with neuropathy symptoms.Nerve health, metabolism, and sensory perception are all aided by B-complex vitamins. B-complex lacks are rather prevalent, and a deficiency can develop after only a

Benign Tumor Types and their Treatments

Image
Tumors are uncontrolled growths of cells that serve no purpose. Benign tumors are not cancerous tumors. Cancer can invade nearby tissues and spread to other parts of the body. When it comes to benign tumors, the outlook is typically very positive. The danger comes from benign tumors pressing on vital structures like blood vessels or nerves. Thus, sometimes they require treatment, and other times they do not. Benign tumors and their causes Benign tumors are often caused by unknown factors. However, benign tumor growth may be linked to: Radiation exposure and other environmental toxins The genetics of an individual Regimen Stress Trauma or injury on the local level The inflammation or infection of the body Benign Tumors: Treatment It is often not necessary to treat benign tumors. A physician may simply wait to ensure there are no complications. However, if symptoms are severe, treatment may be required. Surgery is one of the most common treatments for benign tum
