Solid tumors
Solid tumors
Solid tumors (/ˈsɒlɪd ˈtjuːmər/), derived from the Latin words 'solidus' meaning 'firm' or 'hard', and 'tumor' meaning 'swelling', are abnormal masses of tissue that usually do not contain cysts or liquid areas. They can be benign (non-cancerous) or malignant (cancerous). Solid tumors may be found in many parts of the body, and they often correspond to the type of cells that they originated from.
Types of Solid Tumors
There are many types of solid tumors, some of which include:
- Carcinomas: These are the most common types of solid tumors, originating from epithelial cells. They can occur in many parts of the body, such as the lungs, breasts, colon, and prostate.
- Sarcomas: These tumors originate from connective tissue cells, including fat, muscle, blood vessels, bone, and cartilage.
- Lymphomas: These are solid tumors of the immune system.
- Gliomas: These are solid tumors that occur in the brain and spinal cord.
Diagnosis and Treatment
Diagnosis of solid tumors often involves imaging tests, such as Computed Tomography (CT) scans, Magnetic Resonance Imaging (MRI) scans, and Positron Emission Tomography (PET) scans. Biopsies may also be performed to confirm the diagnosis.
Treatment for solid tumors can vary greatly depending on the type and stage of the tumor, as well as the patient's overall health. Common treatments include surgery, radiation therapy, chemotherapy, immunotherapy, and targeted therapy.
