Q: There are a number of tools you're going to need to remove the old door and put in the new door. Make sure that you have what you need before you start trying to do this operation. If you don't have these in your house, a trip to the nearest hardware store is in order. Leveler to make sure that everything stays level (you'll have difficulty opening your new door if it's at an angle). Caulk to fix the insulation and framing in place. Hammer and nails, nail set, screwdriver (depends on the nails holding your old door in place) to remove the old door and put on the new door. Tape measure or ruler to measure the old and new doors and frames. Insulation to make it so those winter winds don't start whipping around your door. Wood shims to hold the door at the right level, if needed. Before you start ripping your old door out of its frame you want to get the new door. The size and type will depend on your needs and the size of the door frame. You don't want to get stuck with the wrong-sized door. Wood doors tend to have a nicer look, but they aren't as weather-resistant as fiberglass or steel doors. Steel doors also tend to be the least expensive, while wood and fiberglass tend to be around the same price depending on the style of the door. There's nothing worse than getting all primed to go with your new door only to discover that it is too big or too small. You can avoid this unfortunate situation by taking measurements of the old door and applying those measurements to the new door. To check the width you'll need to measure across the top middle and bottom from stud to stud of the old door. The stud is basically the side of the door. The smallest number is the rough estimate for the width. For door height you're going to need to measure the middle, and both sides of the door from the top of the door to the floor. The smallest number is again going to be your rough estimate. Measure the width of the doorjamb. Check the measurements of the old door against the measurements of the new door you're considering. If they match up closely, then you're good to go. If not, you're going to need to consider a new door. This requires removing the door as well as the existing exterior trim and old insulation. Before you can remove the door and main frame, you must cut the caulking, remove the interior and exterior trim, and remove the 14 nailing boards around the exterior of the frame and any shims or nails sticking out of the trimmer studs. To help minimize dust during the demolition, remove the door towards the end of the process prior to extracting the main frame. Using your hammer and a nail set (or a screwdriver), remove the hinge pins and detach your old door for the hinges. For most hinges you should be able to insert a nail set into the hole at the bottom of the hinge pin and strike it upward with a hammer. Keep driving the pin upward (with the hammer) until it comes out. Score the caulking between molding and wall in order to break the seal. With a pry bar and hammer, carefully remove molding. Pry away the doorjamb, framing, and the threshold. Now you can scrape away the old caulking. You need to measure the width between the side jambs, the head jamb to the seal under the old threshold, as well as the thickness of the wall. The rough opening needs to be a minimum of 1 inch (2.54cm) wider and taller than the outside of the door system you'll be installing. Be sure that the rough opening and the subsill (the section of the floor under which the sill will rest) is level. If needed, use shims or a beveled board to level it. If the door needs to clear an especially high floor, like a thick carpet, a spacer board may be needed. While you're working you should periodically check with your leveler that everything is staying level. If things aren't level you might end up with a tilted door or frame, which will cause problems later on. You particularly want to check that the hinge side is level.
A: Gather your tools. Select the new door. Check that the new door will fit. Remove interior and exterior trim. Create rough opening around frame. Make sure everything is level.

Q: Even though the word "cancer" can strike fear in us the moment we hear it, skin cancer is actually one of the most curable forms of cancer. When caught early, it can oftentimes be removed with no long-term ramifications. The key to curability depends on both the specific type of skin cancer, as well as the time-frame in which it is noticed and excised by a physician. If the skin cancer is either a precursor lesion (a precancerous growth), a "squamous cell carcinoma," or a "basal cell carcinoma," it can most likely be removed and cured. These are types of cancers or pre-cancers that, when caught early, rarely cause long-term consequences. Melanoma, on the other hand, is the most dangerous form of skin cancer. Although it is the least common diagnosis, it is the leading cause of death from skin cancer, and the fastest one to metastasize (spread) to other areas of the body. Fortunately, with early identification, many melanomas can be noticed, excised, and effectively "cured" as well; however, the risk is certainly higher with this subtype and thus of greater concern. When you see your doctor and show them your skin lesion, they will evaluate it and may recommend biopsying (taking a sample of) or excising (completely cutting out) any lesions that are potential cancers. If your doctor recommends a biopsy or excision, they will most likely send you to a medical specialist (a dermatologist, who specializes in skin concerns) to undergo the procedure. A biopsy is done if the purpose is to gather more information i.e. if the goal is to determine the specific diagnosis of the skin lesion, and to assess whether or not it is a cause for concern. There are a variety of ways to perform a biopsy; all can be done easily in your doctor's office. An excision is done if the goal is to completely remove the lesion due to a sufficiently high level of suspicion. Generally, skin lesions can be excised using only local anesthetic (local freezing injected in the surrounding skin with a small needle so that you won't feel any pain). It is a procedure that can most often be completed within one office visit, without needing to go to a hospital. If the lesion is smaller, another option is that your doctor may try "cryotherapy," which uses liquid nitrogen to kill the cancerous or pre-cancerous cells; however, this can only be used for lesions that are small and shallow (i.e. that do not penetrate the skin layers too deeply, otherwise the liquid nitrogen is ineffective). If you have had a skin lesion excised by a doctor, know that they will examine the piece of skin under a microscope after it has been removed. What the doctors are specifically looking for under the microscope is whether or not the margins (i.e. the borders) are "clear." If the margins are "clear," meaning that they show no cancerous cells, then you and your doctor can take confidence knowing that all of the pathological cells have been removed. On the other hand, if the margins show cancerous cells, it indicates risk that the cancer has spread to other parts of your body and may not have been completely "cured." If the margins show cancerous cells, your doctor will speak to you about how best to proceed, and what further forms of treatment (such as chemotherapy) may be needed to give you the best chance of a complete cure. When surgeons or dermatologist remove suspicious spots, they will generally remove at least 1 cm of normal tissue. This helps ensure removal of all cancerous cell.
A:
Understand that most skin cancers are easily curable. Biopsy or excise any worrisome lesions. Evaluate the "margins" after excision.
