A cancerous prostate is shown in this anatomical illustration, focused on the prostate gland. In the image, areas of tumoral growth are visible. Moreover, structural alteration of the gland is observed. Furthermore, the diagram shows its relationship with the bladder and urethra. On the other hand, healthy and affected regions are clearly distinguished.
In this case, the prostate cancer is a malignant neoplasm originating from prostate cells. Additionally, these cells grow uncontrollably. Consequently, a tumor develops and may expand. Likewise, it is one of the most common cancers in older men. For example, its incidence increases with age.
From a pathophysiological perspective, tumor growth disrupts prostate architecture. Moreover, it may compress the urethra. Furthermore, this leads to urinary difficulties. On the other hand, in advanced stages, it may spread. Consequently, bones and lymph nodes may be affected. Overall, this defines disease progression.
Regarding symptoms, a cancerous prostate may be asymptomatic in early stages. However, symptoms appear as the disease progresses. Additionally, a weak urinary stream may occur. For example, patients may experience pain or blood in the urine. Likewise, increased urinary frequency may be present.
On the other hand, risk factors include advanced age and family history. Consequently, screening is essential. Moreover, diagnosis includes prostate-specific antigen (PSA) testing. Furthermore, digital rectal examination detects abnormalities. Overall, the biopsy confirms the diagnosis.
Diagnosis of prostate cancer includes laboratory tests and imaging studies. Moreover, tumor grade is determined. Consequently, staging is established. On the other hand, this guides treatment decisions. Likewise, prognosis can be estimated.
Finally, treatment of prostate cancer depends on stage and patient factors. For instance, active surveillance may be considered. However, advanced cases require surgery or radiotherapy. Additionally, hormonal therapies are effective. In conclusion, early detection improves survival.
