Your small intestine is part of your digestive system. It is a long tube that connects your stomach to your large intestine. Intestinal cancer is rare, but eating a high-fat diet or having Crohn's disease, celiac disease, or a history of colonic polyps can increase your risk.

Possible signs of small intestine cancer include:

• Abdominal pain
• Weight loss for no reason
• Blood in the stool
• A lump in the abdomen

Imaging tests that create pictures of the small intestine and the area around it can help diagnose intestinal cancer and show whether it has spread.

Surgery is the most common treatment. Additional options include chemotherapy, radiation therapy, or a combination.

Cancer is a disease in which abnormal cells in the body grow out of control and form a tumor. Ovarian cancer is a cancerous tumor that forms in the tissues of an ovary. The ovaries are a pair of female reproductive glands that make eggs and female hormones.

There are a few different types of ovarian cancer. The most common type is epithelial cancer. It begins in the cells that cover the ovary.

There are also two related types of epithelial cancer that can spread to the ovaries:

• Fallopian tube cancer forms in the tissue lining a fallopian tube. The fallopian tubes are a pair of long, slender tubes on each side of the uterus. The uterus is the female reproductive organ where a fetus grows during pregnancy.
• Primary peritoneal cancer forms in the tissue lining the peritoneum. Your peritoneum is a tissue lining that covers the organs in the abdomen (belly).

These two cancers are like ovarian cancer, and they have the same treatments. So some medical experts also consider those two types as ovarian cancer.

Some other rarer types of ovarian cancer are malignant germ cell tumors and stromal tumors.

Ovarian cancer happens when there are changes (mutations) in the genetic material (DNA). Often, the exact cause of these genetic changes is unknown.

Most ovarian cancers are caused by genetic changes that happen during your lifetime. But sometimes these genetic changes are inherited, meaning that you are born with them. Ovarian cancer that is caused by inherited genetic changes is called hereditary ovarian cancer.

There are also certain genetic changes that can raise your risk of ovarian cancer, including changes called BRCA1 and BRCA2. These two changes also raise your risk of breast and other cancers.

Besides genetics, your lifestyle and the environment can affect your risk of ovarian cancer.

Certain people are more likely to develop ovarian cancer. They include those who:

• Have a family history of ovarian cancer in a mother, aunt, grandmother, or sister
• Have inherited changes in the BRCA1 or BRCA2 genes
• Have certain other genetic conditions, such as Lynch syndrome
• Have endometriosis
• Took hormone replacement therapy
• Are overweight or have obesity
• Are tall
• Are older, especially those who have gone through menopause
• Have never been pregnant

Ovarian cancer may not cause early signs or symptoms. By the time you do have signs or symptoms, the cancer is often advanced.

The signs and symptoms may include:

• Pain, swelling, or a feeling of pressure in the abdomen (belly) or pelvis
• Sudden or frequent urge to urinate (pee)
• Trouble eating or feeling full
• A lump in the pelvic area
• Gastrointestinal problems, such as gas, bloating, or constipation

To find out if you have ovarian cancer, your health care provider:

• Will ask about your medical history, including your symptoms
• Will ask about your family health history, including relatives who have had ovarian cancer
• Will do a physical exam, including a pelvic exam
• Will likely do imaging tests
• May do blood tests such as a CA-125 blood test

Often the only way to know for sure that you have ovarian cancer is by having a biopsy of the tissue. A biopsy is done during surgery to remove the tumor.

Treatments for ovarian cancer may include:

• Surgery to remove as much of the cancer as possible
• Chemotherapy
• Targeted therapy, which uses drugs or other substances that attack specific cancer cells with less harm to normal cells

Your provider may suggest that you have genetic testing to look for the gene changes that raise the risk for ovarian cancer. Knowing whether you have the gene change may help your provider decide on your treatment plan.

Your cornea is the outermost layer of your eye. It is clear and shaped like a dome. The cornea helps to shield the rest of the eye from germs, dust, and other harmful matter. It also helps your eye to focus. If you wear contact lenses, they float on top of your corneas.

Problems with the cornea include:

• Refractive errors
• Allergies
• Infections
• Injuries
• Dystrophies - conditions in which parts of the cornea lose clarity due to a buildup of cloudy material

Treatments of corneal disorders include medicines, corneal transplantation, and corneal laser surgery.

Even if your eyes feel healthy, you could have a problem and not know it. That's why regular eye exams are so important. Refractive errors are the most common type of vision problem that makes it hard to see clearly. But some eye conditions or diseases don't have any symptoms and can lead to a permanent loss of vision.

Some common eye diseases and conditions include:

• Cataracts, which happens when the clear lens in the front of your eye becomes cloudy. Cataracts are common as you get older and can lead to vision loss.
• Optic nerve disorders, which includes glaucoma. Glaucoma usually happens when the fluid pressure inside your eyes slowly rises.
• Retinal disorders, which are problems with the nerve layer at the back of your eye.
• Macular degeneration, which is a disease that destroys your sharp, central vision.
• Diabetic eye problems, which can cause vision loss and blindness.
• Conjunctivitis, which is an infection also known as pink eye. It can cause pink or red itchy eyes. Some types of pink eye can spread very easily.

Some eye conditions and diseases do not always have symptoms. Early detection through a comprehensive dilated eye exam could help your eye care provider detect diseases in the early stages. Proper treatment could help slow or prevent vision loss.

Get regular eye exams and call your eye care professional right away if you notice any of these symptoms:

• A sudden change in vision
• Everything looks dim
• Flashes of light
• Eye pain
• Double vision
• Fluid coming from your eye
• Inflammation (swelling)

Getting older increases your risk of some eye diseases. Other things that may put you at a higher risk of some eye diseases can include if you:

• Are overweight or obese
• Have a family history of eye disease
• Are African American, Hispanic, or Native American
• Have certain health conditions such as Diabetic eye problems, or high blood pressure

Treatment may depend on the eye condition or disease but can include:

• A new prescription for eyeglasses or contacts
• Use of bright lights or magnifying lenses for reading and other activities
• Medicines
• Prescription eye drops or ointments
• Laser treatment
• Surgery

Depending on your eye condition or disease, treatment may slow vision loss but may not restore vision. Talk to your provider about what treatment is best for you.

Your best defense is to have regular checkups. Be sure to tell your provider if any eye diseases run in your family.

You can also help take care of your vision by making lifestyle changes to lower your risk of health conditions that can cause vision problems. This could include by:

• Protecting your eyes from the sun
• Wearing protective eyewear while using tools or playing certain sports
• Getting regular physical activity
• Staying at a healthy weight
• Quitting smoking (or not starting)
• Eating a healthy diet
