<human>: Summarize the given text in a few sentences.

My cousin passed away this past Friday from complications due to a surgery to remove a cancerous growth in his abdomen. His 43rd birthday would have been this month. He has a wife, 13 year-old son and a 10 year-old daughter that he's left behind.

He used to love to sing and he sang in a local cover band up. Hell, he would sing whenever the opportunity presented itself. The problem is that he invited me several times to go out and see him sing with his band. 

I cannot begin to describe how awful I feel. His passing came without warning...right around Thanksgiving was when I heard about the growth in his stomach. He had surgery for it on the 4th and passed away on the 5th. I remember thinking that it was no big deal, just a growth...I felt confidence in modern medicine that he'd get that growth removed, move on to more treatment and have this cancer kicked. I was wrong in thinking that.

Now what is absolutely eating me up right now is that as I went through calling hours today, I saw so many pictures of him and quite a few were with him and the band. That's when it hit me. He personally invited me to go see him sing and I never took him up on it. I always had "plans". I went out with my friends drinking and partying instead and now I realize how I missed out on seeing someone close to me doing what they loved for my own selfish reasons. I am at a lost for how to articulate the self loathing and despair I feel right now -- how disappointed I feel in myself for being so selfish.

Well, I dug out an old hard drive of my uncle's tonight that I had been meaning to recover pictures from for a year or two now and found a full video taped set of his with his band. I'm uploading it to YouTube and weeping like a baby. The funeral is tomorrow and I plan on having a DVD full of pictures ready for my uncle. I don't know how to present it to him or what he will do when I do present it to him. I hope anger is not a response.

Anyway, thanks for reading this.
<bot>: My selfishness cost me the chance to see my cousin do something he was passionate about before he died and I'm beside myself with guilt and regret.
