Cysts are very common and rarely turn into cancers. But it's extremely important to find out whether what you have is just a cyst or something else. If you feel a lump in your breast and you don't know what it is, have your doctor check it. Some women have cyclical lumps i.e. cysts that appear sometime before the menstruation and later shrink or disappear. These are generally harmless and this condition is called fibrocystic disease of breast.

Benign brain tumors are slow-growing tumors that can be removed or destroyed if in an accessible location. Malignant tumors (brain cancer) are rapidly growing tumors that invade or infiltrate and destroy normal brain tissue. No one is certain why, but some benign brain tumors may change over time to become malignant. Tumors are graded to indicate how quickly they are growing. Today, most medical institutions use the World Health Organization (WHO) classification system to identify brain tumors.

Benign prostatic hyperplasia (BPH) is an enlarged prostate gland . The prostate gland surrounds the urethra , the tube that carries urine from the bladder out of the body. As the prostate gets bigger, it may squeeze or partly block the urethra. This often causes problems urinating. BPH occurs in almost all men as they age. BPH is not cancer. An enlarged prostate can be a nuisance, but it is usually not a serious problem. About half of all men older than 50 have some symptoms.1

Benign probably is derived from the Latin word benigenus which means "a good kind" (bene= well, genus= born of, kind). In theory all benign tumors behave well and do not pose serious danger to the patient. Benign tumors are usually easily separated from normal tissues and therefore they can be removed surgically. However, tumors do not read books, so they are not aware of this sharp definition.

The most definitive and diagnosis of brain tumors are done by analyzing a fragment of the tumor under the microscope by the pathologist. The surgeon removes a piece of the tumor and sends it to the pathologist. Using special tissue staining methods, the pathologist can tell whether the tumor is classified under a benign or malignant category. However, this is only the first step in a patient's management.

Cysts are large (sometimes over 5mm in diameter), hard bumps below the skin surface. They are similar to nodules, with only one exception – they are pus-filled. They can be painful and long-lasting. They may cause scars, especially if they are popped. In such situation they become more painful and the inflammation lasts longer than when they are left alone.

Yes. However, cysts in non-Persian cats are relatively rare, regardless of the cause. So the current theory is that almost all cysts found in Persians and related breeds will be PKD cysts. Dr. Biller will be conducting research to help establish exactly how frequently cysts are found in non-persian cats. This study should help us understand the frequency of non-PKD kidney cysts in Persians, and possibly even provide clues about how they can be differentiated from PKD cysts using ultrasound.

A benign breast condition is any non-cancerous breast abnormality. The most common benign breast conditions include fibrocystic change, benign breast tumors, and breast inflammation. Most benign breast conditions such as fibrocystic change or fibroadenomas (small tumors) do not increase a woman’s risk for breast cancer later in life.

quot;… a few cats with PKD also have cysts elsewhere, such as in the liver and the reproductive tract. Livers can have cystic disease that is not related to PKD." Researching PKD on the web, I have seen references to human PKD being linked to both cysts in other organs and to a certain type of cerebral aneurysm. However, so far, I haven't seen any indication that similar links have been established for feline PKD.

The cause of ganglions is not always clear. Non-occupational factors or conditions such as rheumatoid arthritis have been associated with ganglion cysts. Occupational factors play also an important role in the development of ganglions. Those occupations that require workers to excessively overuse certain joints such as the wrist and fingers pose the risk for ganglion cysts.

Benign Prostate Hyperplasia (BPH) is an enlarged prostate. It is a common non-cancerous condition in older men.

If you have a mole that changes in appearance, there may be reason for concern. A mole that has ragged edges, grows longer in diameter, or has uneven colors or various shades of black, brown, red, or blue could be a sign of melanoma, a type of skin cancer. Mr. Vik Vijh should examine a mole with one or more of these symptoms immediately.

A corpus luteum, or functional cyst, is simply a leftover follicle that has outstayed its normal lifespan. Sometimes, they continue to produce progesterone and estrogen, which may delay the arrival of the next period.

Most are not. Most resting cysts are dormant and do not produce toxins. Once an alga emerges from the cyst to an active stage, though, the ability to produce toxins may recur. Resting cysts of golden alga have not been tested for their ability to produce toxins.

A dermoid cyst is a saclike growth that contains fluid, hair, teeth, or skin glands found on the skin that is present at birth. Cysts may remain small for years then gradually grow larger. Cysts are not completely dangerous but it still needs to be removed to prevent rupturing that causes pain and inflammation.
