Hello.....it's best to know what type of sarcoma your Sister has
before attempting any informational research. There are a large number of different types of sarcoma and each have different treatment options. Without knowing more details of your Sister's sarcoma it would be a mistake to take a statement like "no treatments are available" as gospel. There are treatments available depending on a number of factors. If possible, find out some more details of your Sister's sarcoma before you dive into researching "soft tissue sarcoma". Because of the amount of information available from a wide variety of sources, it can quickly become overwhelming. Your journey with your Sister, and helping by gathering information and knowledge of her illness, will be an important part of her cancer care. It seems overwhelming, but knowledge is power. Wishing you and your Family well during this challenging, life altering time. ❤️
