Testicular cancer is a type of cancer that develops in the testicles, which are part of the male reproductive system. It is most common among young men between the ages of 15 and 35, though it can occur at any age. Early detection is key, as testicular cancer is one of the most treatable types of cancer with high survival rates when caught early. Regular self-exams and awareness of symptoms are vital for early diagnosis and successful treatment.

1. What is testicular cancer?
   Testicular cancer is a malignant growth that develops in the cells of one or both testicles.

2. What are the main symptoms of testicular cancer?
   Symptoms may include a lump or swelling in the testicle, a feeling of heaviness, pain or discomfort in the lower abdomen or scrotum, and changes in the size or shape of the testicles.

3. Who is most at risk for testicular cancer?
   Men between the ages of 15 and 35 are at the highest risk, but it can occur at any age. Other risk factors include a family history of the disease, undescended testicles, HIV infection and previous history of testicular cancer in one testicle increases the risk in the other.

4. What are the common signs and symptoms of testicular cancer?
   Common signs and symptoms include a painless lump or swelling in one testicle, a feeling of heaviness or aching in the scrotum, pain or discomfort in the lower abdomen or groin, and changes in the size or shape of the testicles. In some cases, men may also experience breast tenderness or growth, which is linked to hormonal changes caused by the cancer.

5. How can testicular cancer be detected early?
   Regular self-exams and being aware of changes in the testicles can help detect abnormalities early. A doctor may perform an ultrasound or blood tests to confirm the diagnosis.

6. What are the treatment options for testicular cancer?
   Treatment typically includes surgery to remove the affected testicle (orchiectomy), chemotherapy, and in some cases, radiation therapy.

7. Is it possible to live with one testicle after treatment?
   Yes, most men can live a normal life with one testicle. If necessary, a prosthetic testicle can be placed for cosmetic purposes.

8. Can testicular cancer be prevented?
   There is no known way to prevent testicular cancer, but regular self-exams can help catch it early when it is most treatable.

9. What is the survival rate for testicular cancer?
   Testicular cancer has a high survival rate, with over 95% of men surviving five years or more after diagnosis, especially if detected early.

10. Can testicular cancer come back after treatment?
    While rare, testicular cancer can recur after treatment. Regular follow-up visits with a doctor are essential for monitoring.

11. Are there any long-term effects after treatment for testicular cancer?
    Some men may experience long-term effects such as infertility, hormonal imbalances, or changes in sexual function. However, many men live healthy lives post-treatment with proper care and support.
