Testicular cancer, also known as malignant testicular tumors, is a rare tumor, accounting for 1% to 1.5% of male tumors and 5% of urinary system tumors. In Western countries, there are 3 to 4 new cases per million males per year. Over the past 40 years, the incidence of testicular cancer has increased by more than one fold worldwide, with industrialized countries significantly higher than other countries.
The etiology of testicular cancer is not fully understood at present. According to epidemiological analysis, there are many risk factors, including congenital factors such as cryptorchidism or undescended testicles, familial genetic factors, Klinefelter syndrome, androgen insensitivity syndrome, polyglandularism, and excessive estrogen secretion. Acquired factors are generally believed to be related to injury, infection, occupational and environmental factors, nutritional factors, and excessive use of exogenous estrogen during pregnancy. Genetic studies have shown that testicular cancer is associated with the translocation of the short arm of chromosome 12, and changes in the P53 gene are also related to the occurrence of testicular cancer.
Testicular cancer is more common in people aged 15 to 35, usually manifested as painless masses in the affected scrotum. About 20% of patients first experience scrotal pain, and more than 27% of patients experience local pain. Physical examination often shows enlargement of the affected testicle, firm consistency, and loss of normal elasticity. Ultrasound examination is the preferred examination for testicular cancer, and routine examination should be performed for suspected cases. Chest X-ray examination is generally considered the most basic imaging examination, and can detect lung metastases larger than 1cm. Abdominal and pelvic CT are the best methods for detecting retroperitoneal lymph node metastases, and can detect lymph nodes smaller than 2cm. MRI and PET (Positron Emission Tomography) are not superior to CT in retroperitoneal lymph node metastases and are not routine detection methods. Serum tumor markers mainly include alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and lactate dehydrogenase (LDH), of which LDH is mainly used for the examination of patients with metastatic testicular tumors. Placental alkaline phosphatase also has certain reference value for the staging of seminoma. Patients with tumor markers that do not increase cannot be excluded from the possibility of having testicular tumors.
In recent years, the survival rate of testicular cancer has changed greatly, from 60% to 65% in the 1960s to more than 90% in the 1990s, making the treatment of testicular cancer a successful model of comprehensive treatment for solid tumors. The improvement of the cure rate of testicular cancer depends on correct clinical and pathological staging, the progress of imaging, the improvement of serum tumor marker detection, the advancement of surgical methods, the correct selection of chemotherapy regimens, and the progress of radiotherapy.

1. What are the causes of testicular cancer
Testicular cancer is not common, accounting for only 1% of all malignant tumors in the body, and is more common in young and middle-aged adults. Testicular cancer can be divided into germ cell tumors and non-germ cell tumors in histology.
Etiology:
1. Among the innate factors, cryptorchid patients have the highest incidence, followed by hereditary and testicular feminization syndrome, which are more likely to occur.
2. Postnatal factors are mainly caused by injury, followed by hormones and infections, leading to secondary atrophy of the testicles, cellular degeneration, and the formation of tumors.
2. What complications are easily caused by testicular cancer
Surgical treatment for testicular cancer will remove one testicle, will not cause infertility, and will not affect your sexual ability. If your surgery involves lymph nodes, you may experience difficulty in ejaculation. Radiation therapy for testicular cancer can interfere with sperm production, leading to infertility. For some men, sperm production may be limited for one or two years before healing.
Certain chemotherapy drugs can cause infertility, while others may not. When using chemotherapy drugs, you should consult your doctor. In most cases, storing sperm for future use is relatively successful, and sperm can be cryopreserved if you want to start a family life after trying to recover fertility.
3. What are the typical symptoms of testicular cancer
1. Painless enlargement of the testicle, with a sense of weight in the substance, the mass is not clear from the testicle, and the light transmission test is negative.
2. Tumor metastasis or cryptorchidism, palpable mass in the abdomen.
3. Chest examination, breast enlargement indicates that the tumor has systemic endocrine effects.
4. How to prevent testicular cancer
The cause of testicular cancer is closely related to diet, personality, and environment. In terms of diet, foods planted and bred with hormones are the most dangerous, followed by incorrect cooking methods of food, such as barbecue, fried, baked, and overly greasy foods, which are also the root causes of testicular cancer.
1. In terms of diet, foods planted and bred with hormones are the most dangerous. Foods such as barbecue, fried, baked, and overly greasy are also the root causes of tumors; foods grown with pesticides and fertilizers should also be avoided. Do not eat leftover meals, which contain carcinogenic nitrites. Eat more root and stem vegetables: such as sweet potatoes, taros, corn, chestnuts, etc.; meat should be mainly white meat, followed by red meat: such as fish is white, pork is red.
2. Keep a regular schedule, avoid places with polluted air or work, and also stay away from radiation equipment appropriately: for example, computers, induction cookers, microwave ovens, and mobile phones should be kept away from the sleeping area; for places with loud noise, stay away appropriately.
3. Maintain a positive mood, as personality has a significant impact on the testicles. Because the testicular area belongs to the endocrine system, personality can easily affect it. Clinical surveys have found that a large number of people with testicular hyperplasia or tumors have negative personalities, unopenness, long-term depression, etc. It should be noted that in life, emotions should be vented reasonably, not suppressed, and problems should be thought about positively. For example, actively seeking solutions to problems instead of waiting for solutions.
5. What laboratory tests are needed for testicular cancer
1. Laboratory examination Tumor markers (TMs), AFP, HCG, LDH lactate dehydrogenase, PLAP placental alkaline phosphatase, especially AFP and HCG, provide extremely valuable references for the diagnosis, staging, treatment response monitoring, and prognosis of testicular germ cells.
2. Ultrasound examination is of great value in the diagnosis of scrotal contents diseases, with a correct diagnosis rate of 97%, and can directly and accurately measure the size and shape of testicular tumors. In addition, it has diagnostic value for lymph node metastasis of testicular tumors and abdominal organ metastasis.
3. Frontal and lateral chest X-rays to understand the condition of the lungs and mediastinum.
4. CT can more sensitively detect lung metastasis and retroperitoneal lymph node metastasis, having replaced intravenous urography and lymphangiography, and can also detect lymph node metastasis foci with a diameter less than 2cm.
6. Dietary taboos for testicular cancer patients
While treating testicular cancer, patients should also pay attention to their daily diet. The following introduces the diet taboos for testicular cancer patients to assist in treatment.
Foods that testicular cancer patients should eat
1. It is recommended to eat more anti-testicular tumor foods: turtle, cat meat, kelp, sparrow, crucian carp, pork bladder, buckwheat, walnut, litchi, hawthorn, loofah, lettuce, umeboshi.
2. For obvious feminization symptoms, eat dog meat, dog tendons, sea horses, prawns, eels, oysters, turtle meat, walnuts, mutton, goat kidneys, and sparrows.
3. For lumbago, eat taro, chestnuts, plums, lychees, loofah, prawns, abalone, red dates, sea horses, and jellyfish.
4. For infection, eat vegetables, bitter melon, dregs of bean curd, eels, yellow asp, crabs, and toon.
What foods should testicular cancer patients not eat
1. Avoid smoking, drinking, and all spicy and stimulating foods.
2. Avoid moldy, salted, fried, and greasy foods.
3. Avoid warm and hot and positive foods such as mutton, dog meat, chives, animal tendons, etc., except for feminization symptoms.
