Summarize the following:
If the result of your stool test comes back as negative for blood (or DNA), you can take confidence in knowing that your risk of colon cancer at this time is very low. Of course, no test is perfect, so there is always the slight possibility of a testing error, but more likely than not you are not at risk. Your doctor will advise you to proceed with your life as normal. No further testing will be indicated at this time. The stool test is generally repeated every one to two years for people 50 and older, in order to ensure regular screening. Make a note to yourself to follow up with your family doctor again at this time for a repeat stool test. If the result of your stool test comes back positive, you will need to proceed with further investigations at this time. The next step is a colonoscopy, which is where a tube is inserted through the anus all the way up your colon so that your doctor can directly visualize the walls of the colon and look for any suspicious lesions or polyps. If there are any, these can be biopsied at the time of the test and evaluated under the microscope for the presence of cancer. If your colonoscopy shows nothing suspicious, you are in the clear and safe to go on with life as normal. If your colonoscopy reveals colon cancer, you will need to consult a medical oncologist (a cancer specialist) about how best to treat you colon cancer. It is important not to get overly worried about a screening test. This is because the purpose of the screening test is not to diagnose cancer, but rather, to figure out who is at a higher risk and as such needs to have a colonoscopy (which is the official diagnostic test). If you test positive for blood in your stool, there is a chance that you have colon cancer, but it is not diagnostic. If possible, try not to worry too much until you have followed through with the actual colonoscopy. Also, the good news is that, if you receive regular screening, colon cancer can be caught early in the stages where it can be treated and cured (90% of colon cancers caught early are able to be cured).

summary: Take comfort if you receive a negative result. Proceed with a colonoscopy if you receive a positive result. Understand that a positive stool test (the self-screening test for colon cancer) does not necessarily mean you have cancer.

To avoid damaging the pump, shut it off before draining the water. It will be in a chamber inside the RV. Look inside the storage bay above the fresh water tank. Flip the switch to stop the pump. No water will circulate in the RV, so make sure you won't be needing it for about 5 hours. Running a pump while dry can cause it to overheat, so always shut the pump off first. Go to the water heater, which is located outside the RV and near its back end. Turn it off first if it's active or you feel heat coming from it. First, flip the pressure relief valve switch at the top of the heater. Then, look for a nozzle near the bottom-left corner of the heater. Pull the plug out, then replace it once the water has drained. The water heater is located inside a square box on the RV and is covered by a removable panel. The water heater can overheat and burn out, so make sure it is off before draining the water. The hot and cold water are located at the lowest point underneath the RV. They look like 2 capped pipes hanging down from the RV's floor. They stand out a lot, so they're easy to spot. Twist the end caps counterclockwise by hand to drain the water from the lines. The lines are often colored red and blue. Depending on your RV, they may both be colored white instead. You will need to reach underneath the RV to access these pipes as well as the fresh water tank line. To keep the RV still, park on a level surface. You can place chocks on the wheel, but these usually are not necessary. The water tank can usually be accessed underneath the RV, close to the water lines. You may see a brightly-colored spigot sticking out from a square, white box. Pull the plug out of the line. If the water doesn't begin draining, turn the spigot's knob clockwise to open the line. Most water filters and purifiers are external, but check for an interior filter around the fresh water tank inside the RV. The filter will look cylindrical, often colored white or blue. Twist the hose off by hand to remove the filter from the system. Consider changing the filter inside the cylinder to avoid reintroducing bacteria into your clean tank. You can get a replacement filter online or wherever camping supplies are sold. Filters are made in a standard size. Before you begin cleaning out the water tank, check the drains again. The plug should be inserted in the water heater's drain line. Also, replace the caps on the water lines and plug the fresh water line if you haven't already. If all the lines are closed off, no more water should be leaking out. Watch for any signs of leaking as you clean the tank.

summary: Turn off the RV's water pump. Drain the water heater. Open the water lines beneath the RV. Drain the fresh water tank. Detach any water filters hooked up to the water lines. Close all of the drains.

Summarize the following:
The process involved a brush rapidly spinning to buff away scarred skin, removing darkness while leveling the skin for smoothness. It's not an invasive procedure and it is a quick fix to removing light surface scars. The procedure exfoliates the scarred skin by blasting tiny crystals at it. Then, as the brush moves across it scrapes off the scar to reveal new skin underneath. It's very much like dermabrasion, except that it is tougher, removing a thicker layer of skin to ensure scars and other bodily marks are gone for good. Microdermabrasion can also be done at home through kits sold at drugstores or grocery stores. These usually contain a brush and cream you can manually use to scrub scars (and other blemishes) away. For scars that have thickened over time and may be too difficult to sand off or lighten with creams, you can simply cover it with un-scarred skin. By using an instrument that pulses laser light directly on to the scar, a dermatologist or surgeon performs this to break down scar tissue. Once its broken down it is naturally re-absorbed in to the body. The benefit of laser treatments is that it is ideal for almost all skin types; the intensity of the pulses are adjusted to patients' specific skin tones.
summary: Erase a scar with dermabrasion. Replace a scar with new skin underneath with microdermabrasion. Graft skin from elsewhere on the body over top a scar. Laser away scars to guarantee their riddance.
