![]() Now let's learn the words for the front, rear, left and right sides of the boat. What Are The Front, Back, Left, and Right of a Boat Called? Common types of navigation lights are red and green sidelights and an all-around white light, specific to powerboats. Most boats are also equipped with navigation lights.When docking your boat, you fasten a rope or cable to the cleats. Abeam, The bearing of an object 90 degrees from ahead (in a line with the middle of the ship). On the top of the boat are metal fittings called cleats. Get away from the ship, as in an emergency.The cross-section of the stern, where you attach an outboard motor, is called the transom.The gunwales provide extra rigidity for the hull. At the upper edges of the boat's hull are the gunwales.Let's review some more boating terms, starting with the body of a boat. But before we head out on the water, we need to learn some of the specific terms that are used to describe common parts of all boats.įor example, did you know that the two sides of a boat are called "port" and "starboard", not left and right? The extra treatments might increase the chance of curing the cancer.What a great day to go boating. You might have extra treatment if doctors suspect there are micrometastases. This information is important in treating cancer. whether lymph nodes removed during an operation contained cancer cells – if the lymph nodes contained cancer cells this shows that cancer cells have broken away from the original cancer (but there is no way of knowing whether the cells have spread to any other areas of the body).the grade of the cancer (how abnormal the cells are) – the higher the grade, the more quickly the cancer grows and the more likely for cells to spread. ![]() whether there are cancer cells in the blood vessels in the tumour removed during surgery – if cancer cells are found then the cancer is more likely to have spread to other parts of the body.The other boat should slow, stop, or reverse until the stand-on vessel has taken its chance to pass safely. previous experience – doctors collect and publish this information to help each other This vessel is expected to pass through the stern.Doctors base this on a number of factors: But for most cancers, there is no blood test that can say whether a cancer has spread or not.įor most cancers, doctors can only say whether it is likely or not that a cancer has spread. These are sometimes called tumour markers. These may show that there are metastases in the body that are too small to show up on a scan. ![]() They are too small to show up on any type of scan.įor a few types of cancer, blood tests can detect certain proteins that the cancer cells release. Micrometastases are areas of cancer spread (metastases) that are too small to see. This 2 minute video is about the lymphatic system. But some may survive and grow to form tumours in one or more lymph nodes. In the lymph glands, the cancer cells might die. It also traps damaged or harmful cells such as cancer cells.Ĭancer cells can go into the small lymph vessels close to the primary tumour and travel into nearby lymph glands. The lymphatic system is a network of tubes and glands in the body that filters body fluid and fights infection. Platelets are blood cells that help the blood to clot. This could also help the cancer cells to move into the surrounding tissues. The white blood cells in our immune system find and kill some cancer cells. Others cancer cells might die because they get battered around by the fast flowing blood.Ĭancer cells in the circulation may try to stick to platelets to form clumps to give themselves some protection. Of the many thousands of cancer cells that reach the bloodstream, only a few survive to form a secondary cancer. This is quite a complicated process and most cancer cells don't survive it. ![]()
