tumors occur when cells divide and grow excessively in the body.
A tumor, also known as a neoplasm, is an abnormal mass of tissue which may be solid or fluid filled. A tumor does not mean cancer tumors can be benign not cancerous, pre malignant pre cancerous, or malignant cancerous. There are many different types of tumors and a variety of names for them their names usually reflect their shape and the kind of tissue they appear in. Put simply, a tumor is a kind of lump or swelling, it does not necessarily pose a health threat.
When doctors use the term tumor they are talking generically and not about the size of the lesion. A mass usually refers to a lump which is at least 20 mm 0.787 inches in diameter at its widest point, while a nodule is less than 20 mm at its widest point.
Symptoms depend on the type and location of the tumor. For example, lung tumors may cause coughing, shortness of breath, or chest pain. Tumors of the colon can cause weight loss, diarrhea, constipation, iron deficiency anemia, and blood in the stool.
Some tumors may not cause any symptoms. Others, such as pancreatic cancer, do not usually cause symptoms until the disease has reached an advanced stage.
The following symptoms may occur with tumors:
Loss of appetite
3. Types of Tumors
Benign tumors include uterine fibroids and melanocytic nevi skin moles. They are circumscribed and localized and do not transform into cancer.
Potentially malignant neoplasms include carcinoma in situ. They are localised, do not invade and destroy but in time, may transform into a cancer.
Malignant neoplasms are commonly called cancer. They invade and destroy the surrounding tissue, may form metastases and untreated or unresponsive to treatment, will prove fatal.
Secondary neoplasm refers to any of a class of cancerous tumor that is either a metastatic offshoot of a primary tumor, or an apparently unrelated tumor that increases in frequency following certain cancer treatments such as chemotherapy or radiotherapy.
Rarely there can be a metastatic neoplasm with no known site of the primary cancer and this is classed as a cancer of unknown primary origin
4. Causes of Benign Tumors
What causes a benign tumor to form? Often the cause is unknown. But the growth of a benign tumor might be linked to:Environmental toxins, such as exposure to radiation
Local trauma or injury
Inflammation or infection
5. Treatment of Benign Tumors
In many cases, benign tumors need no treatment. Doctors may simply use watchful waiting to make sure they cause no problems. But treatment may be needed if symptoms are a problem. Surgery is a common type of treatment for benign tumors. The goal is to remove the tumor without damaging surrounding tissues. Other types of treatment may include medication or radiation.
