Why is Chemotherapy Given in Cycles?

A friend recently asked why chemotherapy infusions are spaced out. Is it to allow the body a chance to recover between treatments, or is chemo actually more effective when given in cycles? How does it work?

The answer is a bit of both. Traditional chemotherapy involves drugs that are toxic for rapidly dividing cells. The theory is that because cancer cells are dividing very quickly, they will succumb to the toxic chemotherapy quicker than normal cells would. The fact that chemo affects rapidly dividing cells also explains their typical side effects; hair loss because hair follicle cells are constantly dividing, nausea and diarrhoea because the cells lining the digestive system are constantly dividing and so on. So if you take too much chemo too soon, then normal cells would be affected even more, which in turn could lead to even more nasty side effects. 

But it’s also important to remember that the cancer cells in a tumour are at various stages of the cell cycle. The cell cycle is a programme that every cell goes through during growth and division - cells first need to double their DNA and then divide into two. 

The way chemo works is by causing DNA damage, so that cancer cells kill themselves. This happens through a process known as ‘apoptosis’. So a chemotherapy infusion kills all the cells that are in the DNA synthesis phase of the cell cycle, but doesn’t affect cancer cells that are in the other stages. By spacing it out and giving an infusion a few weeks later, the doctors are able to target the cells they couldn’t get the first time around. Normal cells usually repair the damage from chemotherapy more effectively than cancer cells, so damage to cancer cells should progressively build up without causing permanent damage to normal cells

When I explained this to my friend, she mentioned how "it’s a lot like waiting for dandelions to get big enough so they can be ripped out effectively. It’s much harder when they are tiny. But you want to actually get to them before the flowers set seed". It’s a brilliant analogy, and explains really well why chemotherapy is given in cycles.

Ad Astra wins $10 million NASA contract for deep space rocket
From The Tico Times: Ad Astra, the rocket company founded by Costa Rican astronaut Franklin Chang, announced a $10 million contract with NASA to develop deep-space propulsion technology. Spread out over three years, the public-private partnership will help Ad Astra develop its VASIMR prototype engine for in-space travel around the Earth, to the moon or – one day – on a mission to Mars.

Lots of cool info & mind blowing stuff to make you happy about humanity.
Today they have Sam Coniglio from Cosmic Lifestyle Corporation, a company hoping to make space travel less frontier-like & turn it into a comfortable, human experience.

Introduction
I am in love with finding things out & traveling the world. Both are hobbies & my career.

I like to drink coffee & beer...& wine...& brandy.

I love to read.

I like starting political/religious discussions in any bar, leading to a run away, catastrophic melt down of friendships, alliances, & public peace. 

---

'OMG!' Religion & Reason
I am atheist. Though I do think religion is interesting as a cultural phenomenon, and could be seen as art; and like art, religion <strike>is not a method to understand the world around me</strike> can help me to view & understand my emotional relationship w/ the world. 
-Religion & science are two different things:
--Religion is a set of beliefs & conclusions based on culture & faith.
--Science is a method of understanding through testable predictions & consistent observations

If you are not questioning your beliefs, then you are willfully ignorant, may be afraid to find they are incorrect, & are missing out on lots of fun. This goes for myself, which is why...

...I love my religious friends & prefer to not live in an echo chamber.
---

Warning: Politics! *Gasp!*
I would consider myself libertarian, but it is more complicated than that (because economics, humans, society, & social sciences are really complicated) . 

Finding out the boundaries of society's reach & inherent human rights. I am for strong defense of individual rights.

I am extremely wary of federal & military power.

I believe I am the only entity to make decisions about what is best for me, but I'll take reasoned recommendations into consideration.
---

NASA is Govt, & NASA is good...right?
Global/Govt collaboration in the sciences (especially space exploration) is extremely important in making 'frontier' bleeding edge technologies feasible for the private sector (e.g. NASA paving the way, SpaceX & others picking up the trail).

-OTOH, Government & money do not mix; it is inefficient & expensive. People will milk the cow (e.g. Boeing & all others who have overly expensive un-innovative technologies that take advantage of the payment structure of NASA Govt contracts.)
---

If I don't continue with a discussion, it is because I have become too heated and/or drunk to respond in a manner satisfactory to my own quality standards. I love discussion/debate so don't let me off the hook.


It not being acceptable to speak of politics & religion in bars is destroying debate & understanding.
Bragging rights
I once started a physical altercation...on the topic of Jimmy Carter.

The Norfolk area doesn't have a lot to offer when it comes to restaurants, so this was a pleasant find. After three trips, they have not failed to deliver delicious food in a decent amount of time. Even when they were packed, they served us well. They also have a nice beer selection. Prices are what you'd expect for a BBQ/bar joint, which is reasonable for the food, service, & atmosphere. The upstairs has a large bar & will often have karaoke. Parking may be a pain & there may be quite a wait if it is the weekend.

The food here was so good, the setting was nice, & staff friendly. It's nice having a small market inside for you to kill two birds with one stone. From the two visits I made, it wasn't packed (weekend lunch).

This place is the standard I use to judge chicken. Their sides are amazing as well, _love_ the Italian salad.

The Hostel was great, & is the birthplace of the ever popular Wodka. Well maintained & high quality facilities; full kitchen, nice bathrooms/showers, clean beds, & great common area. The location is nice; close to a few restaurants & grocery stores, a park, a church, & a couple blocks away from the tram. During my stay (New Years) the majority of folks were younger, but I had no problem sleeping. Had a friendly atmosphere. Only negative is that the laundry facilities are located near the front desk, which is in a separate building.

The only consistent thing I have experienced with Mojo's is cold, disappointing food & messed up orders. The first mishap I attributed to bad luck, even though we called ahead for the large order (6 people). The second time around was not any better. Though, the staff was nice & they have a stage for music on the busy weekends. I had heard such good things about Mojo's, but when it comes to food, it wasn't even close to hitting the mark.

Great beer menu & the food that I had was fantastic. The inside was spacious, dark, comfortable & classy. There is a large bar as well. The servers demonstrated competent knowledge on food pairings, particular beers, beer types, local breweries, etc. Also, on one occasion, the bartender was _extremely_ helpful (pronunciations of certain beers/foods, other places to visit, attaining a table). It made an impression. I do not recall if I ever went here on the weekend, but it was not too loud or extremely busy for my taste; about what you would expect for an average restaurant & bar.
