Although pleomorphic adenomas are benign parotid tumors, it has the potential to turn malignant. The incidence of malignant transformation increases with the duration of the tumor.

Larger adenomas more often have cancers developing in them. Adenomas with a villous growth pattern are also more likely to have cancers develop in them. The most important thing is that your polyp has been completely removed and does not show cancer.

Although commonly benign, a small percentage (15 to 20 percent) will be malignant and diagnosis of these at the earliest possible stage is of critical importance. The risk for malignancy in an adnexal or pelvic mass increases with age.In general, postmenopausal women are at greater risk than premenopausal women.

Although most benign tumors are not life-threatening, many types of benign tumors have the potential to become cancerous (malignant) through a process known as tumor progression. For this reason and other possible negative health effects, some benign tumors are removed by surgery.

Spiculated Masses Unless it is the site of a previous biopsy, a spiculated margin is very suspicious for malignancy. Cancers appear spiculated because of direct invasion into adjacent tissue or because of a desmoplastic reaction in the surrounding breast parenchyma.

Neoplastic polyps include adenomas and serrated types. Most colon polyps are adenomas. Serrated polyps may become cancerous, depending on their size and location in the colon. In general, the larger a polyp, the greater the risk of cancer, especially with neoplastic polyps.

malignant - these tumours are cancerous and can break apart, move around the body and start new instances of the same cancers in a process called metastasis. benign - these tumours are less serious because they are not cancerous, and do not spread.

In most cases, a branchial cleft cyst isn't dangerous. However, the cyst can drain and cause skin irritation. Cysts can also become infected, causing difficulty with swallowing and breathing. Cancerous tumors may develop at the site of a branchial cleft in adults, but this is very rare.

Malignant nodules are cancerous and can grow quickly. They can spread to other nearby tissues and distant organs. Doctors usually call growths that are larger than 3 centimeters (cm) lung masses, and these typically have a higher chance of being cancerous.

Treatment. Overall, the mainstay of the treatment for salivary gland tumor is surgical resection. Needle biopsy is highly recommended prior to surgery to confirm the diagnosis. More detailed surgical technique and the support for additional adjuvant radiotherapy depends on whether the tumor is malignant or benign.

ABSTRACT The incidence of cancer in a pharyngoesoph- ageal (Zenker's) diverticulum was 0.4% among 1,249 pa- tients treated for such diverticula at the Mayo Clinic in a 53-year period. Twenty-four patients with squamous cell carcinoma arising in a pharyngoesophageal diverticulum have been reported by others.

Nabothian cysts can sometimes look like adenoma malignum, which is a rare type of cervical cancer. If people have adenoma malignum, they may experience symptoms such as: painful cramps during menstruation. prolonged or heavier menstruation than usual.

About 5% of carotid body tumors (CBTs) are bilateral and 5-10% are malignant, but these rates are much higher in patients with inherited disease. Familial tumors are found to be 5.8 times more common among patients who have carotid body tumors as compared with patients who have paragangliomas at other sites.

Minor Salivary Glands Minor salivary gland tumors are extremely rare. However, they are more likely to be cancerous than benign. Cancers of the minor salivary glands most often begin in the roof of the mouth.

Both pedunculated and sessile polyps can turn into benign (non-cancerous), precancerous and cancerous polyps.

The virus is usually associated with cervical cancer. A human papillomavirus (HPV) infection can either directly or indirectly cause a malignant tumor to develop in the prostate, according to Australian researchers. Professor James Lawson and Dr.
