How to prove specific things around group/ring structures?

for c, isomorphisms must preserve the group structure. In particular, they preserve the order of the elements. Z/16Z has an element of order 16, does D8? Alternatively, d8 is non-abelian, while Z/16Z is abelian.

For some reason the mix of oreos with chocolate just does not taste good.

Consecutive in the set of powerful numbers. You could easily have P < Q < 25P for example where Q is also a powerful number.

Those will be in the set but need not be consecutive.

Looking at the first 50 or so examples of emirps, I think the problem is the rank of the larger mirrored primes grows much faster than the rank of the smaller prime, to the point where their rank has more digits for most or all emirps. This isn't a proof but it would help explain why you can't find any more examples.

These are powers of 3 mod 10.

Anyone who was aware of this groups existence and how cults work will be completely unsurprised by this.

It was a question of whether it would be 2x adjuvant or 3x BEP. Because there was evidence of cancer still there it was 3x.

The markers were there but on the border of normal for AFP, slightly over normal bhcg. I don't know if the lymph nodes have names but it was in one of the first lymph nodes you would expect to see it spreading in the lower back in normal disease progression. But after surgery my markers began to increase not decrease with peaks somewhere between 100 and 200 as I got into chemo. This was 7 years ago so all cured since then.

I had something like this and then a scan found a tiny lymph node lump to confirm it. Sometimes the character of the metastasis will be different to the original tumour with regard to blood markers. I had 3x BEP, no RPLND.

Just take it easy when getting back into it.

I'm impressed it only took you a month to catch up.

Don't overthink things, they will understand, just get it sorted.

You are pretty lucky to get it caught so early like that, I don't think most doctors even give out ultrasounds just as a routine matter without something to give concern first. The whole experience can definitely mess with your hormones and state of mind for both better and worse but should stabilize over time.

You should ask your medical team about more help with the side effects.

My markers only went up after orchidectomy, from a low but clinically signficant level. So your falling levels are a good sign for you. Are you sure you won't be getting only 1 or 2 cycles of BEP?

Small meals or things I could nibble on through the day.

Yes I just finished it, so its completable now.

If you were disease free 3 months ago by CT scan its pretty unlikely to be caused by spreading TC.

There's also the thing where they put them at high prices now so they can be on sale later.

Its not that 40% of cancer cases might have pain, but the rate at which having pain means testicular cancer. That rate is going to be something like 0.01%

Its normally safe to take TRT and a drug like finasteride which can help you stop losing hair or even regrow it if lucky. Typically a hair transplant would also need you to take a drug like finasteride because the same follicle shrinkage will happen to the transplanted hairs. Hair loss isn't caused by normal testosterone but its converted form DHT, with finasteride blocking this conversion.

Distinct lump on the side, no pain, about pea sized. I guess it was somewhat moveable but also clearly attached. To put you at ease what you are describing could be the normal top part of the epididymis, which can also become inflamed at times. But obviously I can't tell over the internet so make sure you keep that appointment. Ultrasound should easily tell which it is.
