基底和鳞状细胞癌主要统计来源是什么？

Cancer of the skin (including melanoma and basal and squamous cell skin cancers) is by far the most common of all types of cancer. An estimated 3.5 million basal and squamous cell skin cancers are diagnosed each year (occurring in about 2.2 million Americans, as some people have more than one). Most of these are basal cell cancers. Squamous cell cancers occur less often.

皮肤癌（包括黑色素瘤，基底细胞癌及鳞状细胞癌）是到目前为止最常见的癌症类型。估计每年有3.5亿的基底细胞癌及鳞状细胞癌患（2.2亿美国患者，有些病人患不止一种癌）。

The number of these cancers has been increasing for many years. This is probably due to a combination of better skin cancer detection, people getting more sun exposure, and people living longer.

多年来患者不断增加。归根结底是综合因素，皮肤癌检查更先进，暴晒增多，及寿命增长。Death from these cancers is uncommon. It is thought that about 2,000 people die each year from non-melanoma skin cancers, and that this rate has been dropping in recent years. Most people who die are elderly and may not have seen a doctor until the cancer had already grown quite large. Other people more likely to die of skin cancer are those whose immune system is suppressed, such as those who have received organ transplants.

这些癌症死亡少见。大约2000人死于非黑色素细胞瘤，近年来死亡率下降，很多人是因为年老或者没有来得及就医。其他情况死亡是因为免疫系统低下，例如接受过器官移植。

The exact number of people who develop or die from basal and squamous cell skin cancers each year is not known for sure. Statistics of most other cancers are known because they are reported to cancer registries, but basal and squamous cell skin cancers are not reported.

每年到底多少人患上或者死于基底及鳞状细胞癌还不确定。其他类型的癌症统计是因为有登记，但是基底及鳞状细胞癌没有登记。
