What are the symptoms of brain cancer

Typical symptoms of brain cancer

1. Onset

The disease usually progresses slowly, with a course ranging from 1 to 2 months to several years. Some cases may present with acute or subacute onset, and may even result in stroke. The latter is mostly due to the high degree of malignancy of the tumor, rapid progression, or secondary changes such as hemorrhage, necrosis, and cystic changes in the tumor.

2. Increased intracranial pressure

Symptoms include the "three main signs", namely headache, vomiting and optic disc edema.

3. Focal symptoms

It depends on the location of the intracranial tumor. Common focal symptoms include motor and sensory dysfunction, manifested as limb weakness, paralysis and numbness, convulsions or epileptic seizures, visual impairment, visual field loss, olfactory impairment, sensorineural deafness, language impairment, imbalance, intellectual decline, mental symptoms, endocrine disorders, developmental abnormalities, etc. They often form different syndromes.

The exact cause of intracranial tumors is not yet fully understood. Possible causative factors include:

1. Oncogenes and genetic factors

Tumor molecular biology studies have shown that there are two types of genes that are closely related to the occurrence and development of tumors. The activation and overexpression of oncogenes induce tumor formation, while the presence and expression of anti-cancer genes help inhibit the occurrence of tumors.

2. Physical factors

Radiation can increase the risk of tumor development.

3. Chemical factors

The main chemical factors are anthracene compounds, such as methylcholanthracene, benzene, methylnitrosamine, ethylnitrosamine, etc. Among them, ethylnitrosourea is particularly prone to carcinogenesis during the perinatal period.

4. Oncogenic viruses

After the virus invades the cell, it changes its genetic characteristics, causing it to proliferate uncontrollably.

Treatment principles: surgical treatment is the main method, supplemented by radiotherapy, chemotherapy, etc.

Diet adjustment: Brain tumor patients should adopt a high-protein, high-vitamin and high-calorie diet. Protein in the diet can be obtained from animal foods and bean foods, such as fish, eggs, milk and bean products. High-vitamin foods can be eaten more fresh vegetables and fruits, such as apples, oranges and various green leafy vegetables. High-calorie foods can be obtained from easily digestible carbohydrate foods, such as chocolate.
