Medical help for my baby brother

My name is Krista and I am John's oldest sister.  My brother was hospitalized yesterday 1-24-15 due findings of several lymph node mass's with one being the size of a softball, which is also non operative due to it being close to his aortic artery. Due to some hardships that he has endured, he does not have any medical insurance. Dr.'s believe that it is either Leukemia or Metastatic Lymphoma. He also has three beautiful children that need his support. Thank you for your thoughts, prayers and any help that you can provide.

God Bless.
