i need to write about the economical implications of chemotherapy for breast cancer for a coursework but i cant even find how much it costs?
Preferably from the UK

I had surgary on lung in 2007 (non-Small cell)
I had 4 sessions of chemo
I had brain surgary 2008
And 1 shot of radiation

c.3-’ACGGCAATT-5′
d.5-’ACGGCAATT-3′

6.When DNA is replicated during S of the cell cycle, the sequence is maintained but the double strand is not. Each strand of the original double strand accompanies its new complement strand. This process is known as the

a.disruptive DNA replication.
b.conservative DNA replication.
c.semiconservative DNA replication.

e.sliding clamp subunit.

8.Which of the following DNA replicating enzymes is responsible for unwinding the double helix of DNA?

a.DNA primase
b.DNA polymerase I
c.DNA helicase
d.DNA gyrase
e.DNA ligase

9.The DNA double helix is similar to a twisted ladder. What makes up the sides holding the rungs together?

a.phosphate groups only
b.alternating units of phosphate groups and sugars

a.Watson and Crick.
b.Griffith.
c.Avery.
d.Franklin.
e.Beadle and Tatum.
12.You are asked to participate in a clinical trial for a new drug that can activate telomerase. Which of the following is a likely risk of such a drug?

a.decreased capacity for tissue repair
b.increased vulnerability to cancer
c.premature aging
d.decreased telomere length

13.Xeroderma Pigmentosum (XP) is a rare autosomal recessive disorder. Patients with XP exhibit a cellular hypersensitivity to ultraviolet (UV) radiation, a high incidence of skin cancer and premature aging. Based on these clinical characteristics, what is the underlying cause for this disease?

a.defects in DNA repair
b.defects in DNA replication
c.lack of telomerase activity
d.shortened telomeres

14.A scientist developed a procedure that would cause a particular chemical to bind with the nitrogen base adenine. If this chemical were applied prior to S in the cell cycle, what might be a logical prediction of the outcome? (1/2 point extra credit)

a.The DNA replication would proceed except that all adenine would have the chemical bound to it and is incorporated into the new sister chromatids.
b.The DNA replication would proceed except that everywhere an adenine was supposed to be, a thymine was substituted into the new developing strand.
c.The DNA replication would proceed except cytosine and guanine would continue to form base pairs.
d.The DNA replication would stop because if adenine were bound then thymine would not have a complement with which to base pair.

Is radiation necessary and why? Seems like the treatments used do damage to the body, but are they successful? If not, why not? What could we do different?

how much does throat cancer radiation therapy cost i really need to know also if you know how long does it take cancer cells to develope

I worked for veterinarians for 25 years. I was an assistant then later a tech. I had so much skin cancer on my face and forearms. We were as careful as we could be when doing the x-rays. We wore our tags and lead aprons. Still the thought occurred to me this might have been why I had such deep skin cancer. I know sun damage would be common to those areas but I used to lay in the sun and why am I not having the skin cancers on my back too? That is where I always got burned. I started the Veterinarian job in 68 quit in 94 that is a lot of being around and using the x ray machine. Thoughts? Not trying to start trouble just wondering if this could have been a factor. The cancer is all cleared up now. :^)

Thanks for your thoughts Chris
Thanks Dave, since we were behind no doors and actually holding the animals leaning into what we called the horn. I could see it getting my face and arms exposed. Lots of times just a lead glove was laid over our hands. And with a wigging animal it would slip at the wrong time. Nothing on my arms.

So many people asked me why I had so much deep skin cancer on my face and arms. It has puzzled me for a long time and then just yesterday I got to thinking about the radiation exposure. Also when I was young there was some radiation done on my hands for a skin condition. Later it turned out to be a nervous thing causing it. Sigh. So even more radiation.

Thanks again Chris

How much does cancer treatment – radiation therapy, cost?
My grandma has cancer and I need to know how much does cancer radiation treatments cost?
Thank you!!
She is in Russia and I need an approximate cost of this treatment to see if I should bring her here, to the United States, Florida. She has no insurance. I just need an approximate cost to see if we can afford it or if she should do it in Russia.
Thank you!
