拜登前列腺癌到晚期才发现，可能原因是

The US Preventive Services Task Force (USPSTF) recommends against routine PSA-based screening for prostate cancer, particularly for men 70 years and older. They advise that men aged 55-69 should make an individualized decision about whether or not to get screened, after discussing the potential benefits and harms with their doctor. 

 

前列腺癌是生长比较缓慢的癌症，

就是发生了骨转移，

平均也能活个5年6年的，

拜登还是有可能活到90岁。

 

不要动不动就攻击美国的医疗系统。

贵是贵了点，

质量还是不错的。
