Is my partner lying about lung cancer?

I am so sorry to have to ask this, my partner has told me he has been diagnosed with small cell carcinoma in both lungs. He had an appt with a respiratory Dr after having a cough for a few months (this is the only part of this whole saga, I can confirm as true) and was referred for a bronchoscopy. This was done mid Jan. It took two weeks for him to get the results & he said they told him he had sclc in both lungs. He could not tell me what stage it was. He said he would not be accepting any treatment & was going to beat it himself by juicing, zero carbs, whey protein & drinking hydrogen peroxide. I asked that he take me to the oncologist when he received an appt. Nothing for another two weeks, which I thought was odd, I kept asking about it. In the interim, apparently the hospital had called him to come straight down to have blood tests taken ''to see if it had spread' He  then told me on 8th Feb that the oncologist had been calling him & he had missed the calls but had gone that morning and hadn't wanted to bother me at work. The outcome of this appt was that his cancer was in very early stage &  blood tests had confirmed that it hadn't spread (but it's in both lungs?) The oncologist said the treatment would be chemotherapy or immunology & radiotherapy? I have been asking him since if he has had any appts through as, I respect his wishes that he wants to do it 'his way' but he has no way of knowing if it's working without the drs keeping a check on it. I begged him yesterday to call the hospital as it had been too long, something wasn't right. He then '''confessed' last night that he had received an appt in to go to see about surgery and also immunology about 10 days ago but he had declined both. He then said his respiratory Dr (not oncologist) called him to ask why and said to come in and have an x-ray to ''' see how things are doing', he said he went for this on Monday and was told they would send out the results. There has been no mention of any other scans and surely, in a case like this, the Dr would discuss x-ray results there and then? Also we dont  live together, although he stays over at mine 5/7 before this, now 2/7. He has lost a wee bit of weight but not as much as I would have expected, being ill and also on a strict diet. I feel so guilty for suspecting him of lying. Can anyone help, I feel as though I am losing my mind with worry that it is true and also with doubting him. Thank you
