Are there hair follicles on the penis?

Many male friends think that there are no hair follicles on their penis. In fact, there are hair follicles on the penis, so even men should pay attention to the hygiene of their private parts and change their underwear frequently. Female breast cancer is a very familiar cancer. Men also have penile cancer, which is also a tumor of the genitals. The following article introduces penile cancer in great detail. If you don't know much about it, you can take a look.

1. Penile cancer is a common reproductive system tumor. In the 1950s and 1960s, it ranked first in the incidence of male urogenital tumors in China. In recent years, with the improvement of people's living standards and the continuous improvement of medical and health conditions, its incidence has been declining year by year.

2. Most penile tumors are penile cancers that originate from penile epithelial cells. Phimosis and prepuce are recognized as the causes of penile cancer. Penile cancer is a malignant tumor that can be prevented. Studies have found that circumcision in infancy or childhood can effectively prevent the occurrence of this disease. For those with long prepuce that can be turned up, regular cleaning can also prevent cancer.

3. Treatment methods: Nowadays, there are many treatment methods for penile cancer, including surgery, chemotherapy, radiotherapy, laser, cryotherapy and photosensitization, but surgical removal of the cancer is still the main method, among which partial penectomy is the most commonly used procedure. Patients can easily accept it because of its advantages such as simple surgery, effective treatment, ability to maintain partial sexual function, and ability to urinate while standing. Pathological morphological observations have confirmed that although some penile cancers grow outward like cauliflower, they do not infiltrate deeply inward. Therefore, we believe that partial penectomy is a very reasonable and effective treatment method for stage I and II penile cancer. As long as the resection end is more than 2.0 cm away from the edge of the cancer and the normal penis can be retained at 2.0-3.0 cm, it can be used without complete penectomy. Once metastasis is confirmed, radiation therapy or secondary surgical clearance should be performed.

4. Patients with penile cancer often develop enlarged inguinal lymph nodes, which are mostly caused by secondary infection, and only a few are metastasis. Researchers believe that the principles of treatment are: ① When removing the penile tumor, the inguinal lymph nodes that have no signs of cancer metastasis should also be routinely biopsied. If positive, ilioinguinal lymph node dissection should be performed within 2-4 weeks after the operation. ② For patients suspected of lymph node metastasis, a frozen section of the lymph nodes should be examined before removing the penile tumor. If it is positive and the patient can tolerate it, a primary ilioinguinal lymph node dissection should be performed immediately. ③ For patients with larger and harder inguinal lymph nodes that show signs of cancer metastasis, even if the lymph node biopsy is negative, an inguinal lymph node dissection should be performed. ④ If there is an enlarged sentinel lymph node and biopsy confirms cancer metastasis, the surgical scope should be expanded to perform inguinal lymph node dissection. ⑤ Patients who have not undergone inguinal lymph node dissection need to be closely observed for 3 months after discharge. If the local lymph nodes do not shrink but enlarge, a pathological examination should be performed immediately. If positive, an ilioinguinal lymph node dissection should be performed. ⑥ If preoperative lymphangiography confirms inguinal lymph node metastasis or accompanied by iliac lymph node metastasis, an ilioinguinal lymph node dissection should be performed.

5. Urethral stenosis after partial or total penectomy is mostly caused by wound infection, too short urethra retention or ischemic necrosis of the corpus cavernosum of the urethra. Therefore, it is necessary to prepare by local soaking in antibacterial drugs and disinfectants before surgery. During the operation, a part of the tunica albuginea of ​​the corpus cavernosum of the penis is retained on the dorsal side of the corpus cavernosum of the urethra to increase the blood supply to the end. When the urethral stump is cut into upper and lower flaps, the lower flap is slightly larger than the upper flap, and the flap is everted and sutured to form a nipple to widen the tube opening. The retention of an F18-20 silicone catheter can reduce local irritation, keep the urethra unobstructed, and prevent urine from soaking the incision. Removing the catheter after the incision heals has a positive effect on preventing the occurrence of urethral stenosis. Penile cancer is a low-grade malignant tumor with a good prognosis. Therefore, patients with penile cancer should undergo appropriate surgical treatment as early as possible, and at the same time, follow-up should be strengthened. If the cancer recurs, surgery can be performed again, and radiotherapy or chemotherapy can be appropriately combined.
