I would phone the consultant.
This happened to me, 12 years ago when I had cancer. 2 month wait for operation (no one said, but it was the start of the summer holidays, and I'm sure it was because so many were away on hols.
After the op. my chemo was supposed to start within a month. 6 weeks later, nothing. I phoned the chemo ward to be told I had to wait another month. I was quite upset about it, and someone at work recommended I call the consultant's secretary. I did and she told me to leave it with her. An hour later, she called me back and chemo was arranged to start the next day. Same with radiotherapy. Delayed. Consultant sorted it out after I let him know.
It's shocking that you should have to at a time like that, but you have to self advocate or you risk slipping through the cracks
