Prostate and Testicular Cancer: Comparing the Semblances and Dissimilarities
Prostate and testicular cancer, while both affecting the male reproductive system, exhibit significant differences in various key areas. These differences encompass risk factors, symptoms, prevalence, treatment, and prevention.
Risk Factors
Prostate cancer is more common in older men, particularly those aged 60 and above. Factors that may increase the risk include genetic mutations such as BRCA1, BRCA2, and RNASEL, as well as an association with male androgens like testosterone and dihydrotestosterone [2]. On the other hand, testicular cancer is more prevalent in younger men, with the highest incidence occurring between the ages of 15 and 35. Risk factors for testicular cancer include an undescended testicle or abnormal testicle development, family history (although less well-defined compared to prostate cancer), and rare genetic mutations [1].
Symptoms
Prostate cancer often presents with minimal symptoms in its early stages. As the disease progresses, symptoms may include urinary difficulties such as blocking flow, frequent urination, and blood in the urine or semen. Pain in the pelvis, back, or hips may also occur if the cancer has spread. In contrast, testicular cancer is typically characterised by a painless lump or swelling in one testicle, a feeling of heaviness in the scrotum, or a dull ache or sharp pain in the lower abdomen or groin [3].
Prevalence
Prostate cancer is the second most common cancer among men in the United States, with an estimated 248,530 new cases each year. It is also the most prevalent male cancer, with about 3.55 million survivors. Prostate cancer primarily affects older men, usually those 60 years and above. In contrast, testicular cancer is relatively rare, affecting around 1 in every 250 American men during their lifetime. Despite its rarity, testicular cancer is the most common cancer in young men aged 15-35 [1][3].
Treatment
Treatment options for prostate cancer include surgery, radiation therapy, and hormone therapy. Hormone therapy aims to block testosterone to slow disease progression but is not curative on its own. Advanced cases may require combination therapies such as chemotherapy, cryotherapy, and PARP inhibitors. Testicular cancer treatment typically involves orchiectomy (removal of the affected testicle) and radiation therapy, especially for seminomas. Chemotherapy may be recommended for advanced disease [5]. Notably, testicular cancer has an exceptionally high cure rate with treatment due to its sensitivity to chemotherapy and early detection potential [3].
Prevention
Prevention strategies for prostate cancer are not well-defined, but maintaining a healthy lifestyle, such as weight management, regular exercise, and a healthy diet, may reduce the risk. Avoiding smoking and taking 5-alpha reductase inhibitors and aspirin may also help. There is currently no established prevention for testicular cancer, but early detection via self-examination is recommended due to the young age of onset and treatability [4].
In summary, prostate cancer is a common malignancy of older men strongly linked to androgen signaling and genetics, often with subtle symptoms, while testicular cancer is a rarer but highly curable disease of younger men, visible by physical changes in the testicles.

- The connection between male androgens and prostate cancer, coupled with genetic mutations, highlights the importance of understanding health-and-wellness issues related to men's health, particularly prostatecancer.
- Men should be aware of the differences between the symptoms of prostate cancer and testicular cancer, as the former often presents with minimal symptoms while the latter is typically characterized by a painless lump or swelling in one testicle.
- Given the high prevalence of prostate cancer among older men and its relatively low cure rate compared to testicular cancer, health-and-wellness initiatives should emphasize prevention and early detection strategies for prostatecancer, rather than focusing solely on treatment options.
