Tumors can be defined as an abnormal mass of tissue that forms when cells grow and divide more than they should or do not die when they should. Tumors may be benign (non cancerous) or malignant (cancerous). Benign tumors may grow large but do not spread into, or invade, nearby tissues or other parts of the body. Malignant tumors can spread into, or invade, nearby tissues. They can also spread to other parts of the body through the blood and lymph systems, also called neoplasm. All the Tumours of the penis are almost epithelial (covering or lining) origin and usually involve the foreskin (prepuce) or glans.
Penile : Primary tumours of the epididymis are not uncommon, and most are benign. Penile cancer takes place on the glans or inner surfaces of the prepuce, and metastases (secondary growths at distant parts of the body) occur through lymph vessels that travel from the groin and iliac nodes (nodes along the aorta and iliac arteries). The diagnosis is made by a biopsy of the lesion.
Testicular : The testicular tumours, are usually resemble the cells from which they arise of this type, include the hormone-secreting tumours. In general, these tumours are usually benign, and frequently arise in individuals with poorly developed or undescended testes. majority of malignant tumors (cancer) of this type do not reproduce cells resembling those of the tissue of origin. The major route of metastases for these types of tumours is via the lymphatic system. The lymph nodes in the groin and the mediastinum—the region between the lungs—are most commonly involved, but the lungs and liver are also frequent sites of tumour spread. The most common symptom first observed is painless enlargement of the testes. It is diagnosed by a biopsy, or ultrasound.
Prostatic : An enlarged prostate means the gland has grown bigger. Prostate enlargement happens to almost all men as they get older. An enlarged prostate is called benign prostatic hyperplasia (BPH). It is not cancerous, and it does not raise risk for prostate cancer if treated in a timely manner. It has been described in the diseases of the urinary system. Prostate cancer is rare before the age of 50 but increases in frequency every decade thereafter. It is the third most common cancer in males. Like most tumours, prostate cancer has various causes, but it is thought to be influenced by the male sex hormone androgen. The progress of the cancer is so slow that, by the time it produces symptoms of urinary obstruction or sexual dysfunction, metastasis has occurred in many cases, most frequently to the spine, the pelvic bones, or the upper portions of the thighbones. The diagnosis is made by a prostate-specific antigen (PSA) or transrectal ultrasound (TRUS). If preliminary tests suggest prostate cancer, a biopsy is performed to confirm the diagnosis.
