Prostate Cancer
Prostate cancer is health issue affecting men globally. Recent developments highlight the importance of awareness and early diagnosis. The diagnosis of former U.S. President Joe Biden has brought attention to this aggressive form of cancer. It puts stress on the need for effective management strategies and understanding of the disease.
What is Prostate Cancer?
Prostate cancer originates in the prostate gland, a key part of the male reproductive system. The prostate is walnut-sized and located below the bladder. It produces seminal fluid. Prostate cancer is the most common cancer in men across 112 countries. It accounts for 15% of all male cancers. The disease ranks second in cancer mortality among men, following lung cancer.
Risk Factors
Several factors increase the likelihood of developing prostate cancer. Age is a primary risk factor; the risk rises as men age. Family history also plays a role; men with relatives who had prostate cancer are at higher risk. Obesity is another contributing factor. Studies suggest overweight men have a greater chance of developing the disease. Ethnicity is ; African American men face a higher risk compared to other groups.
Signs and Symptoms
In its early stages, prostate cancer may not present noticeable symptoms. When symptoms do occur, they can include frequent urination, difficulty urinating, and painful urination. Other signs include blood in urine or semen, lower back pain, and painful ejaculation. It is crucial to consult a healthcare professional for accurate diagnosis, as symptoms may overlap with benign conditions like an enlarged prostate.
Stages of Prostate Cancer
Prostate cancer is classified into stages using the Gleason score. This score ranges from 2 to 10, with higher scores indicating more aggressive cancer. A score below 5 is not cancerous. Stages 1 and 2 indicate localised cancer. Stage 3 signifies spread to nearby tissues. Stage 4 is advanced cancer that has metastasised to other organs.
Treatment Options
Treatment varies based on the cancer stage and the patient’s health. Early-stage cancers often have favourable outcomes. Active surveillance may be recommended for small, slow-growing cancers. Other treatments include surgery (prostatectomy), radiation therapy, and systemic therapies. Hormone therapy aims to reduce testosterone’s role in cancer growth. Chemotherapy destroys cancer cells, while immunotherapy boosts the immune response against cancer. Targeted therapy focuses on specific mutations causing cancer.
Future Projections
The Lancet Commission predicts a rise in prostate cancer cases from 1.4 million in 2020 to 2.9 million by 2040. This increase is attributed to ageing populations and longer life expectancies. Late diagnosis remains a critical challenge, especially in low and middle-income countries. The Commission advocates for improved early diagnosis systems and screening trials in these regions to mitigate the impact of rising cases.
