While giant cell tumors are typically benign (noncancerous), they can grow quickly and destroy bone close to a joint. (orthoinfo.org)
Giant cell tumors of bone are not inherited. (orthoinfo.org)
Occasionally, the bone weakened by the tumor breaks and causes the sudden onset of severe pain. (orthoinfo.org)
Osteonecrosis and reactive bone necrosis have been observed, as well as clefted space consistent with extensive hemorrhage in the tumor parenchymal has been identified. (ac.ir)

Mammary (or breast) tumors are common in female dogs, but rare in male dogs and cats. (acvs.org)
Surgical removal is recommended for most mammary tumors. (acvs.org)
Mammary tumors are more common in female dogs that are either not spayed or were spayed after 2 years of age . (acvs.org)
The risk of a dog developing a mammary tumor is 0.5% if spayed before their first heat (approximately 6 months of age), 8% after their first heat, and 26% after their second heat. (acvs.org)
Cats spayed before 6 months of age have a 7-times reduced risk of developing mammary cancer and spaying at any age reduces the risk of mammary tumors by 40% to 60% in cats. (acvs.org)
More than a quarter of unspayed female dogs will develop a mammary tumor during their lifetime. (acvs.org)
In female dogs, 50% of mammary tumors are benign and 50% are malignant. (acvs.org)
However, few of the malignant mammary tumors are fatal . (acvs.org)

Adenomas and hamartomas constitute the largest group of benign lung tumors and, thus, deserve detailed descriptions. (medscape.com)
Pleomorphic adenomas (also known as mixed-type tumors) are the most common benign salivary gland tumors. (merckmanuals.com)
Pleomorphic adenomas (mixed-type tumors) can undergo malignant transformation, but this usually occurs only after the benign tumor has been present for 15 to 20 years. (merckmanuals.com)

Some genes are known as tumor suppressors. (healthywomen.org)
Through these processes, the SMARCB1 protein and other SWI/SNF subunits are thought to act as tumor suppressors. (goldenhelix.com)

For most tumors, surgical removal is the most effective option. (merckvetmanual.com)
Dr. Bruce had pioneered a new surgical technique to remove pineal region tumors. (columbia.edu)

Malignant tumors can invade surrounding tissue and spread to distant organs. (merckvetmanual.com)

The ocular tissue where these tumors arise, the uvea, is a densely pigmented layer that lies for the most part between the sclera and the retina. (medscape.com)

Histologically the tumor showed the mass to be a malignant epitheioid gastrointestinal stromal tumor with mitoses in 8 - 9 of 10 high-power fields ( Figure 1 ). (scirp.org)
Have histologically or cytologically-confirmed R/M HNSCC that is considered incurable by local therapies. (who.int)

These tumors are usually asymptomatic, often discovered accidentally during endoscopic or radiologic examinations. (scirp.org)
