They represent more than 20% of all primary brain tumors
Grade II meningiomas, classified as atypical tumors, have a potential for progression to Grade III, which are classified as anaplastic meningiomas. While not all Grade II tumors will progress, factors such as tumor genetics, histological features, and treatment responses can influence this transition. Regular monitoring and follow-up imaging are essential for early detection of any changes in tumor grade.
Meningiomas are relatively uncommon tumors, and their occurrence in teenage girls is particularly rare. They are more frequently diagnosed in adults, especially women aged 40-60. In adolescents, meningiomas account for a small percentage of brain tumors, and when they do occur in this age group, they are often associated with underlying genetic conditions. Overall, while meningiomas can occur in teenage girls, they are not common.
These tumors are usually benign and most often occur in women aged 30-50 years old
Meningioma's are tumors in the meninges, the membrane that surrounds the brain and spinal cord. Most meningioma's are benign though they can rarely be cancerous.

Benign tumors, such as fibroadenomas in the breast or meningiomas in the brain, tend to stay localized and have a capsule that separates them from surrounding tissues. This encapsulation distinguishes them from malignant tumors, which are more likely to invade nearby tissues and spread to other parts of the body.
Meningiomas
They originate in the membranes that enclose the brain and spinal cord (meninges)

Many tumors, or polyneoplasia, means there are more than 3-4 tumors present. Generally this indicates the primary neoplasia (the original tumor) has spread to other organs or lymph nodes.
About 20,000,000 (20 million) people are diagnosed with bone tumors each year.
There are many diseases you can get from kissing, but not tumors, tumors are a mutation in the skin, and it's not contagious, so no you cannot.
