Hodgkin's Disease

My husband and I have been married for 21 years. We have a very solid and happy marriage. We have been through quite a few hard times together. First, I lost my mother suddenly. Second, about 5 years later, my sister died from cancer. Third, his daughter died suddenly. We have weathered the storms and keep coming to the top. Now, we have another storm to weather.
My husband's son-in-law was diagnosed with Hodgkin's disease 5 years ago. He went through radical treatment. The doctors had just told him it was gone when my husband's daughter died leaving behind the sil and a 2 year old son. Very devastating to all of us. It broke my heart to see my husband suffer, sil walked around in a cloud for months and months and, dgs just couldn't understand why his mommy wasn't coming home.

Just before Christmas, sil was told that the Hodgkin's disease was back. They did discover it before it had started staging but it didn't take long for tumors to appear. He has to undergo more chemotherapy, blood cleansing and stem cell transplants. He is not telling his son that the cancer is back because the little guy is just 4 (will be 5 in March) and he really doesn't understand anything about how bad a disease cancer is.

SIL is in the hospital this week but all they are telling dgs is that "daddy is working undercover" (sil is a deputy sheriff) and having to work and will be home soon. I don't agree with this because I have seen that little guy worry himself silly before because he didn't know why he couldn't see his daddy. Don't they understand that when daddy goes away for an extended amount of time and dgs doesn't get to talk to him, the little guy starts worrying that his daddy is going to go away and not come back like his mommy did?

SIL's chemotherapy treatments are Monday through Wednesday all day long. He will be getting these treatments every other week through 4 treatments. Every time sil has to go into the hospital for the treatment, they are going to tell dgs the same story. I don't know what they are going to do later on when they start the more progressive part of the treatment and sil has to stay in the hospital for longer periods of time.

I am so scared and sad for them. This little family doesn't deserve anymore grief. It is so important that sil survive this round with Hodgkin's, it wouldn't be fair for his little man to have to go through life without the daddy that he idolizes.

Please put them in your thoughts and prayers. Thank you.
