Phone rang, I answered it and nobody on the other end.
I checked American Institute for Cancer on Charity Navigator at
They rate American Institute for Cancer as 20 out of a possible 70 on their scoring system--not very good!

Thank you for the information regarding who is calling! Calls have beginning at our home at 8:00AM and continue to at least 9:00 PM. No one on the line when I answer, no message left if I don't answer. I just called the number you gave for the American Cancer Research Institute and told them to take my number off their call list and they politely agreed to do so. We will see. Again, thanks for the information.

Dial back the number and listen to the automated recording from The American Cancer Research Institute, then press 1 and listen further, next press 3 to remove your number from their list and then enter the telephone number you wish to remove, it will play back the number and if it is correct, press 1 - it will take up to 30 days to remove your number from their list. Doesn't take long at all to do this. When you signed up for the National Do Not Call Registry, your number gets removed from most telemarketers database except for these types charities, political organizations and telephone surveys :)

Has called once a day for the past three week (Saturday, Sunday, excluded) Never a message.
I scream at them to no avail
 Sep 06th, 2007
They call every day and don't leave a message. I've already said "no thanks" to a "Cancer Research" caller ID. This ID simply says "Toll Free Call." It sounds like a boiler room that keeps the vast majority of what they collect and gives only a small contribution to Cancer Research.

Get calls from this number all the time.... and they always hang up on me....
 Aug 19th, 2007

I periodically receive a call from this number. Called again today 8/21/06. It says "800 Service" on the caller ID. I don't answer calls from unidentified individuals, so I don't know what there pitch is.

I called the number 866-435-7544 and it was answered as Cancer Research Center. 8/21/06, 9:50 AM

 Aug 08th, 2006
I also get these daily, usually once or twice a day. They don't leave a message, so I don't answer.

We receive a call almost daily. We are on the state and federal do not call list. Must be a computer generated call because many times we answer there is no one there for a while so we hang up immediately knowing it is a telemarketer.
 Aug 05th, 2006
Yup, this is call number 12. Today 8/5 at 12:18 PM. I have a terse little message on my machine that advises these morons of our DNC status. Apparently they don't get it. Losers!
 Aug 05th, 2006
reporting from Mississippi

Number was on my ID --
"Out of area"

 Aug 05th, 2006
They call several times a day; the last one was 8:45 Saturday morning!
 Aug 05th, 2006

So it's not just me getting them. Thought it might be bill collectors.
 Aug 05th, 2006
Being I am on the no call list, I don't want calls from people I hne no interest in. I pay for the phone so have the decency to not call me as I do not want to hear from you.

Just received a hang up call from 866-435-7544 today, 2006-08-03At least once a day I get a hang up call from Unavailable, Toll Free Number, or just an unfamiliar number. If they do not hang up, I tell them I am on a list to not be called on my home phone or cell phone.
 Aug 03rd, 2006
There was no one there when I answered.
 Aug 03rd, 2006
says "No Caller ID"
 Aug 02nd, 2006
Ahh...same call, different day. These losers don't get it. I'm on a state & national DNC and they STILL call, hang up when they get my terse little answering-machine greeting. Many, many calls from these jerks. Several times a day, several times a week. I just laff when I see their calls come thru to my AM. My advice to them: Get a life.
 Aug 02nd, 2006
I do not appreciate phone calls from solicitors! I am on the DO NOT CALL LIST for a reason!
