Carol….welcome to our site. Sorry for your joining us, but glad you are here. We call this cancer a “silent” disease for the reasons mentioned by you; no warning signs of any sort and then it hits you with vengeance. Stay strong, dear Carol and know that you will be able to handle this. The carers will help you guide through the rough and demanding spots and allow for quality time with your Dad. I am sure that others will chime in real soon and wish you a warm welcome including those residing in your country.
Hugs,
Marion
