Basal Cell Carcinoma: Causes, Symptoms, Treatment, and More

Cancer can affect any human body, including the skin. Basaloma (basal cell carcinoma) is a tumor with limited slow growth. Risk factors include: prolonged exposure to sunlight, contact with inorganic compounds of arsenic, increased sensitivity of the skin to sunlight. There is a dense nodule or a group of small nodules that form a small barely rising plaque. After a while, at the center of the lesion, erosion or an ulcer with a thin scaly crust is formed, along the edges of which close nodules close together are visible. Later these nodules disintegrate and an ulcer is formed with a smooth, bright red bottom and dense margins. Symptoms Small shiny, loose nodules (especially on the face...

Hodgkin's Disease: Symptoms, Diagnosis, & Treatment

Lymphogranulomatosis (Hodgkin's disease) is a tumor disease of the lymphatic system, characterized by malignant hyperplasia of the lymphoid tissue with the formation of lymph nodes in the lymph nodes and internal organs. The lymphatic system is a complex of vessels that carry electrolytes, water, proteins, and the like with lymph from the tissue fluid to the bloodstream. It is formed by lymph nodes and vessels, the spleen, thymus gland (thymus) and bone marrow. The lymphatic system is part of the vascular system and complements the venous system, participates in the metabolism of the body and carries away from the cells and tissues various products of vital activity, as well as foreign...

Difference between fibromas and lipomas

Tumors from adipose tissue and connective tissue are a degenerated "mother" tissue, which began to grow too much. Benign tumors of these tissues are called lipomas and fibromas. Almost all benign tumors are characterized by slow growth - they can grow several months or even years. Lipomas and fibromas can be observed in all parts of the body, especially tumors on the skin and subcutaneous tissue. Symptoms Lipoma: Mild painless. Not fused with surrounding tissues. Tumor formation can be freely moved back and forth. Lipoma is depicted in the first picture of this article. Fibroma: Hard, usually painless. It is visible on the skin. Sometimes the tumor rises above the skin....

Pleural Mesothelioma | Treatment, Prognosis & Diagnosis

Pleural cancer (mesothelioma) is a malignant tumor that occurs in the pleura or peritoneum. Pleura - a thin serous membrane surrounding the lungs (visceral or pulmonary) and the internal surface of the thorax (parietal pleura). This serous membrane has a smooth, moist, shiny surface, due to the secretion of a small amount of fluid in it. The pleura is covered with mesothelium - a single-layered flat epithelium lining the serous membranes of the body cavities of vertebrates. Between the parental and visceral sheets of the pleura there is a pleural cavity with a small amount of liquid, which reduces the friction of the sheets with respiratory movements of the lungs, so that they can slide...

Meningioma Brain Tumor: Causes, Symptoms, and Treatment

Meningioma of the brain is a benign tumor originating from cells of the arachnoid shell, less often from the cells of the pia mater or the stroma of the vascular plexus. Characterized by slow growth, compression and displacement of brain structures. Usually meningiomas appear at the age of 35-50 years. They make up about 20% of all brain tumors, are more common in women, can be the size of a fist and weigh up to 500 g. Usually they are soft like a sponge, but in the elderly it is possible to calcify them and turn into hard knots. Symptoms Symptoms depend on the size of the tumor and its location. Characteristic symptoms: Headache. A feeling of compression in the brain. Weakness,...
