The life expectancy of an individual with glioblastoma is contingent on various circumstances. A prognosis can only be determined by a physician knowledgeable about the patient’s condition and treatment options.

Glioblastoma affects people of all ages. However, older persons are more susceptible. It might worsen headaches, nausea and vomiting, disorientation or loss of brain function, memory and visual issues.

Life Expectancy

Glioblastoma is an exceedingly aggressive form of brain cancer, and a very low life expectancy frequently accompanies the prognosis. Just 25% of glioblastoma patients survive more than a year, and only 5% live beyond five years after diagnosed with this kind of brain cancer.

The life expectancy of a person with glioblastoma varies on several factors, including the kind and location of the tumour, the individual’s age and health, and the individual’s general state of well-being. Additionally, it depends on how the tumour treated and what type of treatment the individual receives.

Estimates of life expectancy generated from period life tables, which are based on recorded mortality rates among different age groups at a particular time and place. Similarly, cohort life tables are based on the mortality rates of an ageing group of individuals. These life expectancy estimates utilized in several ways to provide a glimpse of the health and mortality of a community at a given moment.


Glioblastoma is a kind of brain cancer that is extremely aggressive. It is often fatal within 12 to 18 months after diagnosis and is one of the most lethal forms of cancer.

Glioblastoma is frequently treated with surgery, radiation treatment, and chemotherapy. Modern medicines, such as Tumor Treating Fields (TTFields) and targeted therapies, may also be employed to enhance a patient’s prognosis. In certain instances, a glioblastoma patient will get an immune-boosting vaccination. This will help them to combat cancer, which can be quite challenging.

The life expectancy of a patient with glioblastoma depends on the patient’s age and tumour grade. Higher-grade gliomas are more prevalent in older adults, whereas lower-grade gliomas are more prevalent in younger individuals.


Glioblastoma is a deadly kind of brain cancer. It may induce headaches, nausea, seizures, and memory loss, among other symptoms. It can also cause visual issues, particularly on the left or right side of the eye. Some individuals with glioblastoma have a reduced field of vision and difficulty walking or standing upright.

Surgery to remove as much of the tumour as possible is the main therapy for glioblastoma. Radiation treatment  performed after surgery to eliminate any remaining cancer cells.

The most prevalent chemotherapy medication is temozolomide (Temodar). There are many forms of chemotherapy available. Glioblastoma is the most prevalent form of brain cancer and one of the most lethal. It affects people of various ages, backgrounds, and social classes.

Diagnosis of glioblastoma

A diagnosis of glioblastoma made if an MRI or CT scan of the brain reveals a tumour. The tumour is typically located in the brain’s frontal or temporal lobes. For remove as much of the tumour as feasible while preserving as much of the patient’s brain function as possible. Radiation treatment is also beneficial.

Chemotherapy may also destroy or halt the development of tumour cells that cannot be surgically removed. It may be used with targeted treatment, which targets tumour-promoting proteins with medicines. You will require regular follow-ups to assess your condition and ensure that your tumour has not returned (recurred). PET scans may be required if the cancer returns.
