Prostate cancer is the most common cancer among men in the US, with over 248,000 new cases and 34,000 deaths reported annually. Prostate cancer typically grows slowly and remains confined to the prostate gland, but in some cases, it can spread to other parts of the body, including the lymph nodes.
Lymph nodes are small, bean-shaped structures that are part of the lymphatic system. They act as filters for the lymphatic fluid, trapping bacteria, viruses, and cancer cells. The lymphatic fluid is transported through the lymphatic vessels and eventually drains into the bloodstream. When cancer cells break away from the primary tumour and enter the lymphatic vessels, they can travel to the lymph nodes and start to grow, forming secondary tumours.
Causes of prostate cancer spread to lymph nodes
The spread of prostate cancer to the lymph nodes is called lymph node metastasis. It occurs when cancer cells break away from the primary tumor and enter the lymphatic vessels. The exact cause of prostate cancer spread to lymph nodes is unknown, but several risk factors have been identified, including:
- Stage of cancer. Prostate cancer that has advanced to an advanced stage is more likely to spread to the lymph nodes.
- Prostate-specific antigen (PSA) level. A higher PSA level is associated with an increased risk of lymph node metastasis.
- Tumour grade. High-grade tumours are more likely to spread to the lymph nodes than low-grade tumours.
- Age. Older men are more likely to develop lymph node metastasis than younger men.
Symptoms of prostate cancer spread to lymph nodes
In many cases, lymph node metastasis does not cause any symptoms. However, if cancer has spread extensively, it may cause the following symptoms:
- Swollen lymph nodes. Swollen lymph nodes in the groin, pelvis, or abdomen may be a sign of lymph node metastasis.
- Pain. Pain or discomfort in the lower back, hips, or legs may be a sign of lymph node metastasis.
- Difficulty urinating. If cancer has spread to the lymph nodes near the bladder, it may cause difficulty urinating.
Diagnosis of prostate cancer spread to lymph nodes
If your doctor suspects that your prostate cancer has spread to the lymph nodes, they may order one or more of the following tests:
- Imaging tests. Imaging tests such as CT scans, MRIs, or PET scans can help identify the location and extent of lymph node metastasis.
- Biopsy. A biopsy involves taking a small sample of tissue from the lymph node and examining it under a microscope to determine if cancer cells are present.
- Blood tests. Blood tests such as PSA levels can help determine the risk of lymph node metastasis.
Treatment of prostate cancer spread to lymph nodes
The treatment of prostate cancer spread to lymph nodes depends on several factors, including the location and extent of lymph node metastasis, the stage of cancer, and the patient’s overall health. Treatment options may include:
- Watchful waiting. If cancer has spread only to a few lymph nodes and is not causing any symptoms, your doctor may recommend watchful waiting.
- Surgery. Surgery may be an option if the cancer has spread to a limited number of lymph nodes. The surgeon may remove the affected lymph nodes and the prostate gland.
- Radiation therapy. Radiation therapy can be used to shrink the tumours in the lymph nodes and reduce the risk of further spread.
- Hormone therapy. Hormone therapy can be used to reduce the level of testosterone in the body, which can slow down the growth of cancer cells.

Prostate cancer spread to lymph nodes is a serious complication that can significantly impact a patient’s prognosis and quality of life. It is important for men to be aware of the risk factors and symptoms of lymph node metastasis and to undergo regular prostate cancer screenings to detect the disease at an early stage.
If you have been diagnosed with prostate cancer spread to lymph nodes, it is important to work closely with your healthcare team to develop a personalized treatment plan that meets your individual needs and preferences. Your treatment plan may involve a combination of surgery, radiation therapy, hormone therapy, or other treatments, depending on the location and extent of lymph node metastasis and other factors.
In addition to medical treatment, it is important to maintain a healthy lifestyle and to manage any symptoms or side effects of treatment. This may involve making dietary changes, getting regular exercise, and seeking support from family, friends, or a healthcare professional.
Prostate cancer spread to lymph nodes is a serious condition that requires prompt and effective treatment. With early detection and appropriate treatment, many men with lymph node metastasis can achieve good outcomes and maintain a good quality of life. If you have any concerns or questions about prostate cancer or lymph node metastasis, be sure to speak with your healthcare provider.
