A tumor refers to an abnormal growth or mass that occurs within the human body. It is a broad term commonly used in the medical field to describe the presence of an uncontrolled or excessive cell division, leading to the development of an abnormal lump or cluster. Tumors can manifest in various parts of the body, including organs, tissues, bones, and blood vessels.
Tumors are broadly classified into two categories: benign and malignant. Benign tumors are non-cancerous growths that do not typically spread or invade surrounding tissues. While they can still cause health issues depending on their location and size, they are generally considered less severe and have a lower risk of complications. Malignant tumors, on the other hand, are cancerous and have the potential to invade adjacent tissues and spread to distant parts of the body through a process called metastasis.
The causes of tumors can vary and may include genetic mutations, exposure to carcinogens, inflammation, hormonal imbalances, and certain infections. Depending on the type, size, and location of the tumor, different signs and symptoms may be present, such as pain, swelling, changes in bodily functions, or the formation of palpable lumps.
Diagnosis of a tumor usually involves medical imaging techniques, such as X-rays, ultrasounds, or MRI scans, as well as biopsy procedures to examine the abnormal tissue cells under a microscope. Treatment options for tumors depend on their nature and extent, but may include surgical removal, radiation therapy, chemotherapy, targeted therapy, immunotherapy, or a combination of these approaches. Regular monitoring and follow-ups are often necessary to assess the tumor's progress and ensure early detection of any recurrence.
