CASE 2
Risk factors for Ca?Conclusions
The incidence of muscle-invasive disease has not changed for 5 years.
Active and passive tobacco smoking continues to be the main risk factor, while exposure-related incidence is decreasing.
The increased risk of developing bladder cancer in patients submitted to external beam radiation therapy, brachytherapy or a combination of external beam radiation therapy and brachytherapy must be taken into account during patient follow-up. As bladder cancer requires time to develop, patients treated with radiation at a young age are at the greatest risk and should be followed up closely.The estimated male-to-female ratio for bladder cancer is 3.8:1.0. Women are more likely to be diagnosed with primary muscle-invasive disease than men.
Currently, treatment decisions cannot be based on molecular markers.

Bosniak category
Features Work-up
I A simple benign cyst with a hairline-thin wall that does not contain septa, calcification, or solid components. It measures water density and does not enhance with contrast material.
Benign
II A benign cyst that may contain a few hairline-thin septa. Fine calcification may be present in the wall or septa. Uniformly high-attenuation lesions of < 3 cm, which are sharply marginated and do not enhance.
Benign
IIF These cysts might contain more hairline-thin septa. Minimal enhancement of a hairline-thin septum or wall can be seen. There may be minimal thickening of the septa or wall. The cyst may contain calcification that might be nodular and thick, but there is no contrast enhancement. There are no enhancing soft-tissue elements. This category also includes totally intrarenal, non-enhancing, high-attenuation renal lesions of > 3 cm. These lesions are generally well-marginated.
Follow-up. A small proportion are malignant.
III These lesions are indeterminate cystic masses that have thickened irregular walls or septa in which enhancement can be seen.
Surgery or follow-up. Malignant in > 50% lesions.
IV These lesions are clearly malignant cystic lesions that contain enhancing soft-tissue components.
Surgical therapy recommended. Mostly malignant tumour.
