Define tumor

A tumor is an abnormal growth of cells that form a mass or lump. Tumors can be benign (non-cancerous) or malignant (cancerous). Benign tumors do not spread to other parts of the body and are not life-threatening, while malignant tumors can invade nearby tissues and spread to other areas, potentially causing serious health problems.

A tumor is an abnormal growth of cells in the body. It can be either benign or malignant. A benign tumor is non-cancerous and does not spread to other parts of the body. It can usually be removed and does not typically cause serious health problems. On the other hand, a malignant tumor is cancerous and has the potential to invade nearby tissues and spread to other parts of the body through a process called metastasis. Malignant tumors can be life-threatening if left untreated. To understand the characteristics and details of tumors, one can refer to medical textbooks, websites, or consult healthcare professionals such as doctors or oncologists, who specialize in the diagnosis and treatment of tumors.

A tumor is an abnormal growth of tissues that forms when cells multiply uncontrollably. Tumors can occur in various parts of the body and can be benign (non-cancerous) or malignant (cancerous). Benign tumors typically do not spread to other parts of the body and are localized to a specific area. Malignant tumors, on the other hand, invade nearby tissues and can spread to other parts of the body through a process called metastasis. Tumors can be classified based on the type of cells they originate from, such as carcinomas (epithelial tissue), sarcomas (connective tissues), lymphomas (lymphatic tissues), and leukemias (blood or bone marrow cells). The signs and symptoms of a tumor can vary depending on its location and size, and they can include pain, swelling, lumps, changes in skin color, weight loss, fatigue, and abnormal bleeding.
