Kidney cancers. Kidney cancers do not often cause early symptoms and the majority of renal neoplasms have an accidental finding during radiological investigations.
The appearance of blood in the urine not associated with the presence of urinary infection or recurrent urinary infection should lead to investigations such as abdominal ultrasound. Excessive fatigue, unjustified weight loss, low-grade night fever with no other viable reason, palpable masses in the abdomen and persistent soreness on the side of the body are delayed symptoms.
An ultrasound can identify the renal tumour while computed tomography (CT) in addition to distinguishing the nature of the mass provides more information on the extension of the disease. Other diagnostic tests are magnetic resonance and urography, which evaluates the urinary tract and the smooth passage of urine. This test is the most relevant in case of blood in the urine and it is mainly used to assess the presence of cancer in the urinary tract, urethra, bladder, ureters, and renal pelvis.
Bladder Tumours. The cardinal symptom for the diagnosis of this cancer is macro-haematuria (blood in urine), although the disease can be completely asymptomatic at onset. In cases of suspected bladder cancer, diagnostic procedures are based on ultrasound, radiology (urography and CAT), magnetic resonance and endoscopic methods, such as cystoscopy. The latter is the introduction of a fibre optic instrument into the bladder through the urinary tract and allows evaluation of the inside of the bladder and potentially taking samples of suspicious tissue for analys. A further diagnostic aid is provided by searching for cancer cells in the urine sample via urinary cytology. CAT, PET and bone scintigraphy are also useful for evaluating whether the cancer has spread beyond the bladder, involving other organs.
Testicular cancers. The main symptoms are the presence of an often painless nodule, an increase in testicular volume, swelling, a change in the testicular consistency, a feeling of heaviness in the testicle, a sharp pain in the abdomen or groin, or lastly, fluid in the scrotum.
If a malignant cancer in the testes is suspected, the indications are for urological objective examination, blood tests that include beta HCG, LDH markers and alpha-fetoprotein markers, as well as testicular ultrasound. CT scan of the chest, abdomen, and pelvis is used for staging and for visits following up therapy.
Adrenal cancers. The majority of adrenal cancers are often found accidentally during radiological investigations.
