Oncology
The tumor is defined as a mass that forms when the cells come out of their pattern and grow out of control. The tumors are divided into two types: benign, and the other malignant. The benign type is characterized by its inability to spread and the ease of its removal without causing harm. The malignant species is characterized by spreading to other parts of the body if not treated early, and is rapidly growing.
Types of tumors
Polyps
They do not spread to other organs or physical areas or invade nearby tissue, such as cancerous tumors, which are usually life-threatening and slow-growing, but may cause symptoms and signs based on their location. For example, if they are close to nerves, they may cause symptoms that need to be removed.
Malignant tumors
Malignant tumors are cancerous; they spread to many organs and regions through lymphatic channels and blood vessels, and they invade adjacent tissues. Symptoms of malignancies may include:
Treatment of tumors
Polyps
In many cases, the doctor is only waiting for the waiting of the benign tumors without any treatment, but if there are problems, but if symptoms appear on the patient then they must be removed surgically without affecting the neighboring tissues, There are other treatments for non-surgical benign tumors, including radiotherapy and pharmacotherapy.
Malignant tumors
Treatments for malignant tumors include:
- Chemotherapy, a drug therapy.
- Directed therapy is a treatment that uses drugs or other substances and is designed to attack cancer cells accurately. This method of treatment results in slight damage to non-cancerous cells.
- Immunotherapy: A treatment performed by a person’s immune system to fight cancer cells.
- Radiotherapy: It destroys cancer cells using high-energy molecules or waves.
- Surgical treatment.
