Understanding Bladder Cancer in Totality
Posted by Pierce Jonsson in About CancerThe bladder is an important organ in a person to expel urine containing waste products from the body, but it is also subject to a dangerous form of cancer called bladder cancer. This is a disease that takes place in the bladder and is listed as the fourth most occurring cancer in males and eighth in females. The cancer tumors may form either on the bladder wall surface, or inside the wall and underlying muscles; the former is regarded as superficial bladder cancer whereas the latter is regarded as more severe forms. This type of cancer is commonly found in the older generation although there is no age restriction. However, it is at least twice as more prominent in men.
Risk factors of bladder cancer include cigarette smoking, diet and gender. The carcinomas from an infected bladder are found to be related to a prolonged exposure to harmful aromatic amines used in the chemical-related industry as found in dyes, nitrates, leather dust, solvents, paints, benzedine, inks, combustible products, textile and rubber. Carcinogen takes around eighteen years to develop its symptoms, after exposure to it.
It is not scientifically proven yet that diet can effect the development of bladder cancer although a rich fruit and vegetable and low fat is helpful in reducing the risk. Other related health problems include UTI, kidney stones, serious bladder irritation and stones in the bladder but may not be actual causes of bladder cancer.
About 25% early stage patients of bladder cancer exhibited no symptoms of the disease until they experience painful urination, urinate blood, frequent urination and dribbling. But some of these are not distinct to the illness which could possibly have been due to other conditions that are non-cancerous such as cystitis and prostate infections.
Cancers are categorized as superficial or invasive. When the cancer impacts just the internal lining in the bladder, it is termed superficial; if it has gone deep into the bladder’s muscular layers, it is invasive. In the US, scaly-type cell carcinomas is not more than 5% worldwide while bladder carcinoma is more than 75% in underdeveloped countries alone. A transitional-type cancer, Urothelial carcinoma, is most common in the US.
A bladder cancer patient has 80% total recovery if the cancer is diagnosed early in the bladder. Cystoscopy is accompanied by biopsy. Other scans such as CT and Ultrasounds, Angiography and urinalysis can also be performed.
There are various types of treatment for bladder cancer like surgery, chemotherapy, biologic therapy and radiation. The cancer stage and what grade it is of are important information for proper treatment. Bladder tumors which are superficial can be removed easily with an appropriate treatment with chemotherapy to prevent recurrence. Invasive cancer would opt for a total removal of the bladder with an external urinary appliance.
Research has discovered some new compounds which can react positively towards transition cell bladder cancers and are now on trial runs with chemotherapy. BCG immunotherapy is found to be the best therapy for invasive cancers as it has live Mycobacterium bovis strains to halt superficial tumors from recurring. Acupuncture patches and herbal treatments are alternative treatment options with some impact.
Quitting cigarette smoking will definitely reduce the risk in developing bladder cancer and to prevent future tumors. As this disease has a 50%-80% recurrence rate, physicians recommend a regular 3 month cystoscopy screening for 2 years after the treatment. Drinking lots of fluid lowers the rate of recurrence of this disease.
The final outcome of this disease is dependent on what stage the cancer is at, what type and where it has spread in the body. The survival rates are that the superficial type enjoys a prognosis of 82%-100% 5-year survival; the tumor that is contained in the bladder wall without spreading to other areas or organs, gives a 60%-75% 5 year survival after a surgical procedure to remove the tumor with chemotherapy as well as radiation therapy; invasive tumors that are in advanced stages especially in the lymph vascular, experiences 30%-50% 5-year survival, with a radical total bladder removal.
