Metastatic Prostate Cancer: Definition and Characteristics
In order to understand metastatic prostate cancer, it is essential to know its definition and characteristics. This form of cancer occurs when prostate cancer cells spread from the prostate gland to other parts of the body, such as the bones, lymph nodes, or other organs. Unlike localized prostate cancer that remains within the prostate gland, metastatic prostate cancer has the ability to invade other tissues and organs, leading to more advanced stages of the disease.
Metastasis is a complex process that involves cancer cells detaching from the primary tumor, entering the bloodstream or lymphatic system, and then traveling and establishing secondary tumors in distant sites. The ability of prostate cancer cells to metastasize significantly impacts the prognosis and treatment options for patients.
When prostate cancer cells metastasize, they typically spread to the bones, particularly in the spine, pelvis, and hips. However, metastatic prostate cancer can also affect other organs such as the liver, lungs, and lymph nodes. The spread of prostate cancer to these distant sites can cause a range of symptoms, including bone pain, urinary problems, fatigue, weight loss, and other complications.
Metastatic Prostate Cancer Characteristics:
- Often develops in patients with previously treated localized prostate cancer
- Has a higher risk of recurrence and disease progression compared to localized prostate cancer
- Can be detected through imaging tests, such as bone scans, CT scans, or MRI
