Shannon's Run

• An estimated 700,000 Americans are living with a primary brain tumor

  • Approximately 71% of all brain tumors are benign

  • Approximately 29% of all brain tumors are malignant

  • Approximately 58% of all brain tumors occur in females

  • Approximately 42% of all brain tumors occur in males

• An estimated 88,970 people will receive a primary brain tumor diagnosis in 2022

  • An estimated 63,040 will be non-malignant (benign)

    • Meningiomas are the most commonly occurring primary non-malignant brain tumors, accounting for 39% of all tumors and 54.5% of all non-malignant tumors

  • An estimated 25,930 will be malignant

    • Glioblastoma is the most commonly occurring primary malignant brain tumor, accounting for 14.3% of all tumors and 49.1% of all malignant tumors

• The median age at diagnosis for a primary brain tumor is 61 years

• Males have a 1 in 143 chance of developing brain cancer in their lifetime and a 1 in 188 chance of dying from brain cancer in their lifetime. For females, the chance of developing brain cancer is 1 in 186, with a 1 in 239 chance of dying from the disease

• The average survival rate for all primary brain tumor patients is 75.7%

  • Survival rates vary by age and tumor type and generally decrease with age

  • For non-malignant brain tumor patients, the average five-year survival rate is 91.8%

  • For malignant brain tumor patients, the five-year relative survival rate following diagnosis is 35.6%

    • For the most common form of primary malignant brain tumors, glioblastoma, the five-year relative survival rate is only 6.8% and median survival is only 8 months

• More than 18,200 people are estimated to lose their life because of a malignant brain tumor (brain cancer) in 2022

• There are more than 100 distinct types of primary brain tumors, each with its own spectrum of presentations, treatments, and outcomes

Stages of Brain Cancer

• Grade 1: A grade 1 brain tumor is noncancerous or slow-growing.  

  • Its cells resemble healthy cells in appearance and are often cured with surgery.

• Grade 2: The stage 2 brain tumors are malignant but slow-growing.

  • Its cells under a microscope appear somewhat unusual. 

• Grade 3: The stage 3 brain tumors are malignant and develop more quickly than grade 1 and 2 tumors.

  • When viewed under a microscope, the malignant cells display severe abnormalities. 

• Grade 4: Stage 4 cancer brain tumors develop rapidly and have various abnormal features that can be seen under a microscope.

  • Stage 4 brain cancer timeline is aggressive in which the tumors can spread to other regions of the brain and may even create their blood arteries to keep up with their fast growth.
