Your family can have a history of cancer and based on that its possible to be susceptible to tumors or hemorrages based on cancer history in the family. However, a brain hemorrage can also be caused by a stroke or extremely high blood pressure and not have to be because there's a family history.
If you have had incidents of brain hemorrages and tumors in your family then yes be concerned and go to your doctor for cancer screening. The earlier cancer is caught means the best chance for survival.
Many forms of them are, yes. If you know which kind, you should be able to determine whether it is genetic or not.
yes
brain hemorrhages is not genetic if occur in older age . its happen because of trauma to brain or high blood pressure or atherosclerosis of brain vessels .
What causes brain tumors?
The majority of brain tumors have abnormalities of genes involved in cell cycle control, causing uncontrolled cell growth. These abnormalities are caused by alterations directly in the genes, or by chromosome rearrangements which change the function of a gene.
Patients with certain genetic conditions (i.e. neurofibromatosis, von Hippel-Lindau disease, Li-Fraumeni syndrome, and retinoblastoma) also have an increased risk to develop tumors of the central nervous system. There have also been some reports of children in the same family developing brain tumors who do not have any of these genetic syndromes.
Research has been investigating parents of children with brain tumors and their past exposure to certain chemicals. Some chemicals may change the structure of a gene that protects the body from diseases and cancer. Workers in oil refining, rubber manufacturing, and chemists have a higher incidence of certain types of tumors. Which, if any, chemical toxin is related to this increase in tumors is unknown.
Children who have received radiation therapy to the head as part of prior treatment for other malignancies are also at an increased risk for new brain tumors.
The factors that contribute to the formation of brain aneurysms:
Smoking
Hypertension
Traumatic head injury
Use of alcohol
Use of oral contraceptives
Family history of brain aneurysms
Other inherited disorders: Polycystic kidney disease
there are several types of these like:
A saccular aneurysm (berry aneurysm) can vary in size from a few millimeters to over a centimetre. Giant berry aneurysms can reach well over 2 cm. The aneurysm resembles a sack of blood attached to one side of the blood vessel by a narrow neck. These are more common in adults.
Other types of cerebral aneurysm may involve widening (dilatation) of the entire circumference of the blood vessel in an area, or may appear as a ballooning out of part of a blood vessel. These types of aneurysms can occur in any blood vessel which supplies the brain. Trauma and infection, which can injure the blood vessel wall, can cause such aneurysms.
