A tumor, also known as a neoplasm, is an abnormal mass of tissue .

1. Tumor
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.

2. Symptoms
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
Night sweats
Weight loss

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
  • Genetics
  • Diet
  • Stress
  • 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.

    6. Common Types of Benign Tumors
    There are many different types of benign tumors arising from different structures in the body. These are some of the most common types of benign tumors:
    Adenomas are benign tumors starting in the epithelial tissue of a gland or gland like structure. The epithelial tissue is the thin layer of tissue covering organs, glands, and other structures. A common type of adenoma is a polyp in the colon. Adenomas might also grow in the liver or the adrenal, pituitary, or thyroid gland.
    In most cases, adenomas can be removed with surgery. Although not common, this type of tumor can become malignant.

    7. Diagnosis of Benign Tumors
    Benign tumors are diagnosed using a variety of techniques. The key in diagnosis is determining if a tumor is benign or malignant. This can only be determined with certainty through tests in a laboratory.
    Your doctor may begin by performing a physical examination and collecting your medical history. He or she will also ask you about the symptoms you are experiencing.

    8. When to see a doctor
    Cancer and cancer treatments may cause side effects that require immediate attention. However, it is often hard to know when to call the doctor. For example, you may struggle to differentiate between a common cold and a more serious infection. Therefore, it is important to ask your doctor to explain the potential side effects of your specific type of cancer and cancer treatment, as well as the circumstances under which you should call for help.Some side effects that require immediate attention include infections, deep vein thrombosis a potentially life threatening blood clot, and tumor lysis syndrome a condition that can cause organ failure.

    9. Complications
    Pain. Pain can be caused by cancer or by cancer treatment, though not all cancer is painful. Medications and other approaches can effectively treat cancer related pain.
    Fatigue. Fatigue in people with cancer has many causes, but it can often be managed. Fatigue associated with chemotherapy or radiation therapy treatments is common, but it s usually temporary.
    Difficulty breathing. Cancer or cancer treatment may cause a feeling of being short of breath. Treatments may bring relief.
    Nausea. Certain cancers and cancer treatments can cause nausea. Your doctor can sometimes predict if your treatment is likely to cause nausea. Medications and other treatments may help you prevent or cope with nausea.
    Diarrhea or constipation. Cancer and cancer treatment can affect your bowels and cause diarrhea or constipation.
    Weight loss. Cancer and cancer treatment may cause weight loss.

    10. Preparing for your appointment
    You re likely to start by seeing your family doctor or a general practitioner. If your doctor finds evidence of a pituitary tumor, he or she might recommend you see specialists, such as a brain surgeon neurosurgeon or a doctor who specializes in treating disorders of the endocrine system endocrinologist. Here s some information to help you prepare for your appointment.
