What is a Cataract?

A cataract is a clouding of the clear lens that filters light in your eye. Cataracts can interfere with your vision and can slowly develop over time or can enlarge quite suddenly. Cataracts are often diagnosed on routine eye exams, but sudden changes in vision should be reported to an eye doctor.

Symptoms of a Cataract

Signs and symptoms of cataracts can vary depending on the size of the cataract and how far advanced at is. Some of the most common symptoms of cataracts include:

  • Blurry or clouded vision
  • Light sensitivity
  • Problems with glares
  • Frequent eyeglass and contact lens prescription changes
  • Clouding of the middle part of the eye
  • Halo effect when looking at lights
  • Double vision in only one eye
  • Needing increased light to do activities such as reading, sewing, or puzzles

A cataract may start as a small spot of blurry vision in your eye and get noticeably worse as time goes on. Regular check-ups with your doctor will help to track the development of the cataract and come up with a proper treatment plan.

What Causes Cataracts?

While cataracts typically develop as you age, there are other issues that can lead to cataracts. Injuries to your eye or surgical procedures can damage the lens of your eye leading to cataracts later in life. Genetics and long-term medical conditions such as diabetes also increase your risk of developing cataracts.

Types of Cataracts

There are four different types of cataracts that you may be diagnosed with. These usually differ by how they develop as well as their location.

Nuclear Cataracts

A nuclear cataract usually begins with a disturbance in your near-sighted vision. As the cataract develops, it will become yellow and more cloudy before becoming brown and will eventually cause a disturbance in both close and far vision.

Cortical Cataracts

Cortical cataracts will begin as white streaks throughout the lens that will eventually spread to the middle, causing more vision disturbance as more light is blocked.

Posterior Subcapsular Cataracts

This type of cataract typically starts a small opaque area towards the back part of the lens that sits directly in the pathway of the light trying to come through. Posterior subcapsular cataracts will often spread quicker than most and tend to affect reading vision and vision in bright lights. It often creates halos and glare issues.

Congenital Cataracts

Congenital cataracts are ones that a child is born with or they develop sometime during their childhood. This can often be the result of genetics, infection in the uterus, trauma, or medical conditions such as rubella or myotonic dystrophy.

Cataract Surgery

If your cataracts begin to interfere with your ability to read, drive, or perform routine daily activities, cataract surgery may be the best option for you. During the cataract surgery, the doctor will remove your clouded lens and replace it with a new clear lens that will significantly improve your vision.

Cataract surgery is very safe and is an outpatient procedure that does not require a hospital stay. Your doctor will discuss the risks and benefits or surgery with you if it is the recommended course of action.

While cataracts can cause significant problems with everyday life, they are most often treatable with surgery. If you have any vision disturbance or think that you may have a cataract, schedule an appointment with your eye doctor.

How Important are Your Eyes?

Image is from Think About Your Eyes

Although we at times take it for granted, seeing is undoubtedly one of the most important functions of the human body. The role played by your eyes cannot be underestimated at all since the eyes are helpful in almost all the aspects of your life. In many cases, the eyes have been referred to as the camera of the body. They have been likened to a camera for reasons such as:

  • Both devices perceive images
  • After gathering light, they both focus and transmit it through the lens
  • Both help in creation of images of the surrounding environment

Taking care of your eyes begins with knowing how important they are and the specific functions they have. Below is an outline of the importance of your eyes.

  • Color and Image Perception

As a sense organ, the eyes help in distinguishing different images and colors. The eye’s retina is a part that contains millions of light-sensing neurons called cones and rods. They are responsible for the perception of color details after which they convert the light into electrical impulses. The converted impulses are then sent to the brain for interpretation. The eyes give the vision needed for activities such as driving, reading and making decisions when you are required to choose from various things.

  • Production of Tears

Many people think that tears are only useful when they need to express their emotions like when they are happy or sad. Tears, however, have many other functions such as nourishment of the eyes, vision maintenance, washing away debris and lubrication. Your eyes have a tear system that involves three parts: the glands that form tears, the openings through which tears flow from the eyes and ducts that drain tears into the nose. The eyes are therefore very essential to the production of tears.

  • Keeping us safe

Sight is essential for safety and self-preservation. Life is full of dangerous obstacles, and the eyes help us avoid them. It would be very dangerous to walk around or do different things without the eyes. They are therefore very instrumental in ensuring your safety and provide awareness of any danger within our environment.

  • Connecting with the surrounding

You would never get to connect with the many things that happen in the immediate surroundings. Even if you hear about them, it would not be as good as it would be if you witnessed them occurring. Your eyes give you the ability to perceive movements as well as assess the intentions for different forms of motion. Eyes help in bringing out the beauty of the world around us. Most of our preferences depend on what we see. We like the things which are more appealing to our eyes.

  • Sensing

Other than perceiving images, your eyes help in sensing. There are times when one of your senses could be missing. When you have a cold, for instance, you tend to lose the sense of taste and smell. It, therefore, becomes very different to detect rotten foodstuffs which upon consuming would cause digestion problems. In such a scenario, the eyes take over this work. The only way to distinguish what is edible from the inedible would be by carefully scrutinizing the foodstuffs to identify traces of molds or any other indication of food spoilage.

Due to this, it is important to take care of your eyes. The best way of looking after your eyes is by visiting an optician regularly to get checked. Through this it will be easy to detect any issues and correct them before it is too late, maintaining your quality of life.

Misunderstandings of Cancers


Infographics from

Cancer is a disease that is caused by the division of abnormal cells in the body that are uncontrolled. Some types of cancer cause tumors in the body, while there are other types of cancer, such as leukemia, that do not. There are some misconceptions about cancer that many people have.

All Types of Cancer is the Same

Many people believe that all cancer is the same and that there is one wonder drug to treat the disease. There are over 100 types of cancer and they all cause different symptoms. Each different type of cancer has a different treatment. We know more about some types of cancer, such as breast cancer, and less about esophageal and pancreatic cancer.

There is No Cure For Cancer

Technically, there is no cure for cancer. There is no magic pill that will kill off all the cancer cells in a day, making the patient 100 percent healthy. While there is not a true cure, the individual cancer patient can be cured. Remission is the first step to a cure. If the patient remains in remission for 5 years, they are considered to be cured. While there is no actual cure for cancer, there are treatments that can cure the patient.

Cell Phone Dangers

The idea that cell phones cause cancer is a common misconception. Cell phone technology has advanced rapidly over the past few years. The phones today contain fewer carcinogens than the phones before them. Recently, a study was published by the Danish Cancer Society, which found no links between cell phone use and brain cancer.

Cancer Lumps

Many people believe that if they find a lump or a mass is detected during a screening, that it is cancerous. The truth is, every abnormality is not cancerous. The problem could be a cyst or a benign tumor, which is not cancerous. While it is not always going to be cancer, there are instances where the lump is pre-cancerous or cancerous. This is why regular screenings are necessary.

Artificial Sweeteners Cause Cancer

Since the 1970’s, people have been saying that artificial sweeteners cause cancer. This is because, in 1969, a study was done on the effects of the active ingredient in artificial sweeteners, cyclamate, on mice. When the mice developed cancer, people panicked. What they didn’t know is that the doctors were giving the mice the equivalent of a human drinking 800 cans of diet soda each day. Too much of anything can cause cancer, and artificial sweeteners in moderation will not.

You Need More Than a Positive Attitude

There are some people who believe that just a positive attitude can treat their cancer. While a positive attitude can help, you need more than that when you have cancer. There is more than mind over matter when it comes to cancer. Being positive and even alternative treatments can help, however, you need to take the medications and accept the treatments offered by your doctor.

Surgery Can Cause Cancer to Spread

Decades ago, doctors could only diagnose cancer when it was in advanced stages and surgery was for exploratory purposes. Also, there was no way to tell if all of the cancer cells were removed. Because cancer treatment was so new, people believed that if the doctor tried to remove a tumor, the cancer cells could spread throughout the body. This is not true. Surgery is one of the most effective ways to treat cancer.

There are many misconceptions when it comes to cancer. Most of the misconceptions began years ago and have been since proven false.

Understanding Breast Cancer


Inforgraphic from the CDC

Breast cancer, like any other cancer, occurs when a mutation or abnormal change deforms the genes responsible for healthy cell growth. Such a change could lead to uncontrolled or undesirable cell growth. The cells that result from this also carry the faulty gene combination meaning that the cell growth becomes exponential resulting into a tumor.

The resulting tumor could be either malignant or benign. Benign tumors grow slowly and contain almost normal cells. They do not invade surrounding tissue or spread to the rest of the body hence are not really a big threat.

Malignant tumors, on the other hand, consist of highly mutated cells that not only grow fast but also have the power to invade and affect other parts of the body.

How Does This Relate to Breast Cancer?

A cancer becomes breast cancer if a malignant tumor develops from the breast cells. These could be cells in the milk-producing glands (lobules,) the ducts or sometimes the stromal tissues.

If left unchecked, the cancer can invade surrounding healthy tissue and later make their way to the underarm lymph nodes. If the cells make get to the lymph nodes, they will have unlimited access to other parts of the body and the condition can escalate faster.

The spread of the mutated cells from the initial tumor determines the stage of the cancer. Comparing this against the breast cancer stages chart will give you a visual impression of the infection.

The Causes of Breast Cancer

Contrary to the common belief that most of the breast cancer is inherited, research has shown that only 5 to 10 percent of the cancers result from inherent genetic material mistakes. 85 to 90 percent of the conditions result from abnormalities arising from aging, exposure to mutagens and the natural tear and wear of life.

Staying on Top of Breast Cancer

The best card you could ever deal malignant tumors is by discovering them as soon as possible. The simplest way to identifying tumors before they spread is by taking regular mammograms. Mammograms are x-ray pictures of the breast tissue. They are a sure way to identifying tumors that are too small to feel or detect during a physical exam.

  • Screening mammograms search for any changes in women without any signs of breast cancer. They are an early warning sign and the physician will only act when he or she sees something suspicious.
  • Diagnostic mammograms are taken when you have identified a lump during the physical examination or the screening mammogram. It involves taking x-rays from different angles for better inspection of the anomaly.

While the mammogram is the real deal in identifying breast cancer, a regular physical examination between the regular mammograms will be another early warning strategy. Feel your breasts and underarms looking for:

  • Lumps in or near the breasts
  • Lumps under the arms
  • Thick or firm tissue near the breasts or sometimes under the arms
  • Changes in breast size and shape

Contacting an expert when you spy a lump is always wise. You must note that the breasts will feel lumpy during pregnancy or during your menstruation period. This should cause any alarm unless it persists beyond menstruation or sticks to one part of your breast for a month or two during pregnancy. Only then should you seek medical advice.

Since breast cancer is in essence cancer, understanding cancer in general will help you know the dynamics of breast cancer better. Exploring the different treatment and maintenance options as soon as you get a positive diagnosis will give you a better shot at beating the cancer.
